Re: cksum entire dir??

So you run mtree twice, once against dir1 with the -c option to output the specification for the directory tree to stdout (which you can capture to a file, or pipe straight into the second invocation) and once against dir2 with the output of the first one as input (either in a pipeline, or by using -f with the filename of the captured output).

My understanding is that in general the system does not allow SUID on scripts. The way I have gotten around that (a long time ago) was to create a small binary that exec's the script and making the binary SUID. Well it's all hacks and in my not so humble option like chasing your tail. The assumption is that if someone creates an executable (assumption is programming is C) they are more credible not to make mistakes. That's a fallacy and just plain nuts.

It's nothing at all to do with whether someone writing a compiled language is a better programmer than someone writing an interpreted language. When the OS launches a binary, the file containing the program is opened once.

Re: Established method to enable suid scripts?
On Wednesday 11 May 2011 04:19:29 Devin Teske wrote: The reason that the suid bit doesn't work on scripts (shell, perl, or otherwise) is because these are essentially text files that are interpreted by their associated interpreter. It is the interpreter itself that must be suid. I'm pretty sure that's not the case, although I'm open to correction. The reason the system ignores the suid bit on a script is because of what would happen when it's executed: 1) the script is read from a file called filename and the system notices that it needs to be interpreted by another program. 2) that program is launched and told to re-open the file named filename and execute its contents with suid privilege. The problem is a race condition: there's no guarantee that the filename opened by the interpreter in step 2 is the same file the user executed in step 1. There are two common ways round this: ignore the suid bit; or arrange within the OS to pass a handle to the original file rather than a filename so that the script can't be changed out from under the interpreter.

This could mean almost anything (witness another response which excludes lines

Are you actually trying to extract all the lines inside [XYZ]...[/XYZ] tags?
are the tags guaranteed not to occur on the lines you need to extract, as they

Because (all on one line)
perl -ne 'print if ($check = m{\[XYZ\]} .. m{\[/XYZ\]}) 1 and
$check !~ /E0$/' asdf.txt output.txt
produces the same output as you have above for the test input. (The .. range
operator in scalar context is true as soon as the left-hand expression is
true, and false as soon as the right-hand expression is true. It returns 1
each time it becomes true, incrementing integers as it stays true, and
appends E0 to the last number as it becomes false, which lets you exclude
both endpoints).

I have not been able to ascertain exactly why Java cannot be made functional on a modern FreeBSD system. Other than receiving some useless suggestion about donating money to the Java foundation, or whatever it is called, nobody has responded with an answer. The bottom line is that Java appears to be functioning on other flavors of *.nix, but not FreeBSD. It would seem pretty obvious where the problem lies. Yes. It lies with Sun and Oracle, and the licensing terms that prevent the FreeBSD project from distributing modified Java packages. More generally, the problem lies with companies who won't support FreeBSD but also prevent the project from supporting their product itself. There are strong commercial interests in Linux - IBM, Red Hat, Oracle, to name three - which makes it worth spending some money supporting a product on Linux. (That goes for other products too: nvidia graphics card drivers, flash, wireless networking device drivers...) Even so there are products that have patchy support in Linux too. FreeBSD isn't as attractive a commercial target, since it has no financially powerful backers (that I'm aware of), a small market share, and not much public awareness. Some companies are prepared to sink resources into supporting it anyway, and others are prepared to release the information needed for the FreeBSD project to support their products for them. There are other companies, as I said, that won't do either. I don't think it's fair to blame the FreeBSD developers for that; nor indeed to expect the FreeBSD developers to be responsible for making Sun/Oracle's Java and the Mozilla Foundation's Firefox work.

I have employed VERP with mailing lists that I controlled. I never noticed any adverse effects. I know of several technical lists like Dovecot that employ it. Obviously, they find it useful. VERP itself is reasonably lightweight, as it modifies the envelope sender address -- something that can be applied during processing by the MTA as part of sending the message. As far as mail delivery goes, that's a very different story -- it goes from one message with tens of thousands of recipients, to tens of thousands of messages each with one recipient. Exactly - you can't batch up all the messages for users at the same domain because they now have different envelope senders. The impact of that on your mail delivery system (and the receiver's SMTP receiving system) depends on whether you have lots of individual subscribers, or several large groups. Having said that, I looked up VERP last night to check that I was right about the extra load, and came across a reference to VERP being the idea of DJB, and being acceptable to qmail users because there's no penalty load - qmail never batches up messages for the same domain, always sending each one individually.

I'd agree with this too. The idea of the change seems to be to protect people from wasting time downloading and building something which they can't install without resolving a conflict. How exactly was that wasted time? Surely you don't download and build a port you're not going to install? What the change actually does is penalise people who want to download and build regardless of conflicts, to reduce the time between uninstalling the conflicting port and being able to install the replacement.

I tried that and as you predicted, all the bogus stat calls went away. Unfortunately the performance issue did not. :( Back to the drawing board for me! Upon further inspection, it seems as though for each check, Nagios spawns a process that spawns a process that spawns a process that runs the check. I did ktrace -i -t w -p (nagiospid) on Nagios for 30 seconds and the ktrace output contained records from 2365 different processes spawned in that 30 seconds. During that time, I would expect about 800 checks to have run, so it does seem like it's right at 3 processes per check. I just don't think the system can keep up with all that fork()ing without going all out; it's just a limit of the Nagios plugin architecture. You've probably already spotted this, but this behaviour is documented in largeinstallationtweaks.html: ``Normally Nagios will fork() twice when it executes host and service checks. This is done to (1) ensure a high level of resistance against plugins that go awry and segfault and (2) make the OS deal with cleaning up the grandchild process once it exits. The extra fork() is not really necessary, so it is skipped when you enable this option. As a result, Nagios will itself clean up child processes that exit (instead of leaving that job to the OS). This feature should result in significant load savings on your Nagios installation.'' It can also be enabled separately in nagios's main config file - child_processes_fork_twice is the option to look for.

Unless I've got this wrong (in which case I'm sure someone will shout), there were initially two 64-bit instruction sets, amd64 from AMD and ia64 from Intel. ia64 saw so little uptake that Intel started using the AMD instruction set, but amd64 is still the appropriate description for most 64-bit processors these daya regardless of manufacturer.

Even so, several people put time and effort into helping you, and suggesting ways you could reach a quicker solution when you made it clear what your personal effort limit was. Due to diligence and a great deal of my time, I managed to save all the files that were on the system and recovered the XP disks so everything can now be re-installed and used. Actually, it was also a great deal of time donated by other busy people around the world. The only victim in the end is FreeBSD as I will never touch it again. It has been going downhill since way back; but I think I just preferred to stay with my illusions and tolerated the waste of time and effort reconfiguring, searching for answers and reinstalling, rebooting and the whole shebang under the aura of learning. So learn I did. Don't touch it; it sucks. There are other systems better than FBSD, so g'bye all. :o :-P ``I can't use it, therefore it's rubbish''. That's fine, no-one forced you to use FreeBSD in the first place and I doubt anyone minds that you don't want to use it any more. Personally, I do think it's a pity, because FreeBSD (in my experience, since FreeBSD 4.5) is stable, easy to use (once you have the basic Unix concepts on board), and astonishingly well-documented. It's also supported by one of the friendliest and most knowledgeable communities I know. I don't recognise FreeBSD or its user community in your description and I hope your tirade, on an extremely publically archived mailing list, doesn't put other people off trying it.

I may be misunderstanding what you've been saying over the last couple of days (I can understand your frustration, but your questions would be much clearer if you didn't let it spill over into chippy remarks about FreeBSD like the above). Let me summarise what I think you've said, and what I think it means, and please, correct me if I'm wrong. You run a custom kernel, and you decided for your latest system upgrade that you would use freebsd-update, which as far as I know doesn't work with custom kernels. You discovered this and tried to move your custom kernel aside and put a GENERIC kernel in place for the upgrade, rebooted in the middle of the process, and now when you try and boot up, your system can't find a kernel - which is why the bootloader is asking you to tell it where to look. If that's the case, your data should all still be there in the original slices/partitions (others have told you how to check that). You are likely to struggle to get the system booted unless you can work out where to direct the bootloader to find a kernel, but you may well be able to inspect the data on the disk if you boot a LiveCD (which is a version of FreeBSD that runs from the CD - there's one in the release set). Given the problems you've encountered so far, and the level of effort and learning that's acceptable to you in your situation to try and resolve it, I would suggest you go and buy a new hard drive (they're not expensive these days compared with the cost of your time), and fit it alongside your messed-up drive in your computer. You can then do a fresh install on the new drive, get everything set up the way you want, and then retrieve the data from the old hard drive (various ways to do this: mounting the drive and simply copying files, dump and restore of complete filesystems, etc). You've also thrown in a new problem, which is that X doesn't recognise your mouse. Unfortunately, that doesn't have much to do with FreeBSD. It's a result of a decision by the X developers to require a hardware abstraction layer - you probably need to enable hal and dbus. Googling will put you on the right track.

Editor in minimal system (was Re: The question of moving vi to /bin)
This whole thread only really got started because I questioned Manish Jain's assertion that there was no editor available in /bin. To summarise: There are several editors available ranging from ed (49604 bytes) and ee (60920 bytes) (both with two library dependencies) to emacs (in ports; 5992604 bytes and 50 library dependencies in my installation) and probably beyond. One of them, ed, is available in /bin and therefore in single-user mode. Two of them, ed and vi, are available in /rescue and therefore in single-user mode even when something horrible happens and libraries are broken (although /rescue/vi is currently slightly broken itself due to the termcap issue which is being fixed in -CURRENT and I hope will be MFC'd). Anyone who wants /usr/bin/vi available in single-user mode can install FreeBSD with one large partition; or mount /usr once in single-user mode. The original poster suggested that the fix for not having vi in /bin was not to have any editor at all in /rescue, which comprehensively misses the point of /rescue. The only argument that's been advanced for moving vi seems to be ``vi should be in /bin because that's how I want it''. I find that argument unconvincing, but it's not up to me. I'm open to a sensible argument, if anyone has one.

I might annoy a few people (which would gladden me in this particular case), but ed was just one of Ken Thompson's nightmares which he managed to reproduce in Unix with great precision. By no stretch of imagination would it qualify as an editor, because an editor can meaningfully edit only what it can first show. And ed has never had anything to show. A modern operating system like FreeBSD should really be kicking ed out of the distribution completely : bad ideas don't have to be necessarily perpetuated just for the sake of compliance with the original concept of Unix. Hold on. I didn't claim it was a *good* editor - I was reacting to your suggestion that /bin didn't contain an editor at all. ed(1)'s interface is certainly minimal, but it's easy enough to list lines in the file you're editing, contrary to what you seem to be saying - to list every line of the file, try the two characters , l. However, if you want a more visual editor, perhaps /usr/bin/ee (which is just over 10K bigger than /bin/ed) would do? You also suggested doing away with ed and /rescue/vi altogether. You may not need statically-linked tools very often, but when you do need them, you *REALLY* need them. Don't suggest throwing them away without thinking through the implications.

Bear in mind that /usr/bin/vi is over 300K, compared to the whole of /bin which is ~950K (if you avoid double-counting entries like /bin/csh and /bin/tcsh which are hardlinks to the same file), so you need to convince people who think /bin should stay small to let it grow by a third to save people learning ed(1).

Once you've recompiled the kernel you also need to use suiddir in the mount options for any filesystem where you want file ownership to be inherited from the directory. It's described in the kernel notes and in the mount manpage as a dangerous option which opens security holes. I notice that you mention setGID as well, which under sysV-derived systems allows file to inherit group ownership from the directory. If that's what's wanted, you don't need to do anything, as the behaviour that's optional on sysV systems like Linux is the default behaviour on FreeBSD.

Intel has been convicted of many of these things in courts in Asia and in Europe. The fact that the US system is too supine to take action against these companies doesn't make the EU ``arrogant''. Let's not forget why Unix took off and expanded the way it did: once upon a time the US courts did take antitrust seriously, and prevented ATT using its telco monopoly to expand into market domination of the computer business. The spinelessness of the American court system is that they do not take legal action against European countries that practice reverse discrimination, or the outright breach of copyright laws, etc. I know, you socialists also abhor copyright laws. The concept of an individual actually benefiting from his/her hard work and not having to share it with every scum sucker who comes begging at his door disturbs you. Whoa.

The reality is almost the exact opposite: the EU is using competition law to try and restore a level playing field, despite

Use fdisk to create your single large slice on the new disk with fdisk -BI ad6 Use bsdlabel -R ad6s1 ad6s1.label to restore the disklabel. If your device name is different from before, you need to edit newfscmds.ad6s1 to change the ad6 to the new device name wherever it occurs, but you then run the newfs commands in the file to create your filesystems with the same parameters (softupdates on/off, etc) as before. You now have the basic structure of your previous disk, ready to have the root, /var/ and /usr dumps restored to make a running system identical to the destroyed one, with one last step: bsdlabel -B ad6s1 to put the boot code on the slice. (I haven't tried this bit, so if you're going to use the boot code from your root partition, which is stored at /boot/boot, you'll need to check whether you can run bsdlabel -B on a mounted disk. If you can, the command would be bsdlabel -B -b /mnt/boot/boot /dev/ad6s1 assuming you mounted /dev/ad6s1a on /mnt). If you have a different device name, of course, you also need to edit your fstab before rebooting.

That's what I suspected you were saying yesterday, and it seems to be wrong. Try this (assuming you haven't already configured/installed net/freeradius2 and security/krb5) cd /usr/ports/net/freeradius2 make all-depends-list make config# select Kerberos make all-depends-list make -C /usr/ports/security/krb5 config# unselect documentation for krb5 make all-depends-list make -C /usr/ports/security/krb5 rmconfig make rmconfig You will get three different lists of dependencies: in the first case, the main port (net/freeradius2) has the default OPTIONS and doesn't depend on security/krb5 or its dependencies. In the second case you will find teTeX and its dependencies in the list as they are dependencies of krb5 in its default setting. In the third case, you have changed an OPTION of security/krb5 to remove its dependency on teTeX, and net/freeradius2 correctly removes the teTeX dependency from its all-depends-list. This certainly looks like all-depends-list correctly taking account of the changed OPTIONS in the target port and all its dependencies. What *is* a problem is make config-recursive, which doesn't take account of any dependencies added as a result of OPTIONS changes made during the config-recursive process. This is relatively easily fixed, as make config-recursive actually runs make config-conditional for everything in all-depends-list, so if you keep running make config-recursive until nothing happens you can be reasonably sure you've dealt with all the unexpected dialogues that might otherwise pop up. This is worth knowing if you like doing overnight unattended installs and don't want to accept default settings (so can't use BATCH=yes). Until I discovered it I had immense frustration setting an installation/upgrade running only to come back the next day and find a dialogue sitting on the screen.

The first three ports/metaports I tried to install after completing the base setup were emacs, TeTeX and the Psi Jabber/XMPP client. None of those was available, and after seeing how few prebuilt packages there were in all categories, I gave up. My personal view is that PC-BSD gives the end user an impressive and reasonably slick computer-as-appliance with some ability to customise and still stay ``on the path''. For people who need that, PC-BSD is what they need. My feeling, though, is that anyone who finds themselves wanting to install a bunch of stuff from outside the PBI system (in other words, from ports, which are still there under the hood of PC-BSD) will soon want to switch to mainstream FreeBSD.

Make that ports tree available as part of this package system and compile a typical desktop set of ports, particularly choosing ones which are large or have many dependencies. When it is all complete release it and start again. Surely quite a wide selection of desktops, wm's and apps could be compiled in a couple of weeks? How is it an improvement over the existing tools? I must be missing something, because it sounds to me like you are merely asking that there be more ports made available as packages than are now offered. I think what you're missing is the suggestion to bundle a set of pre-built packages with a snapshot of the ports tree used to build them. Currently it's difficult to mix and match packages and ports because the versions of dependencies are likely to differ between the package and the local version of the ports tree. If you know you have the same ports tree your packages were built from, you can much more easily combine pre-built packages and local builds from source. This has clear advantages. At the moment, unless you're very lucky with your timing, you tend to find that as soon as you want to build one port from source (perhaps to fiddle with the configuration) you have to stop using prebuilt packages altogether. The drawback I can see is the disk space required to keep several generations of packages online - if the package-port bundle is rebuilt every three weeks, let's say, and you want to keep 6 months' worth of packages online, you need to keep 9 complete versions available. Chris's suggestion is certainly more than just a request for more packages, though.

Re: shell commands - exclusion
On Friday 06 February 2009 02:55, Chris Whitehouse wrote:
I think you should be able to do it with a combination of -prune and
-delete (or -exec rm -rf {} \; ) on a find command. Substitute your
other commands for rm -rf in the -exec above.
I would give you a working example except I can't figure out the syntax
for -prune. Examples from google don't seem to work in (my) FreeBSD.
[skip to the end for a simple answer without the lengthy exposition]
find(1) can be confusing, especially if you think of the ``actions''
( -print, -exec and -delete plus their variants like -ls and -ok ) as
something different from the ``tests'' ( -name and so on), or if you don't
take account of the evaluation order.
A find expression comprises a number of what the manpage calls primaries, each
of which evaluates as true or false. (It may also have a side-effect,
like -print whose side-effect is to print the name). Primaries can be
combined with -and (which is usually implied) or -or. Where -and and -or both
occur, find will group the -anded primaries together before evaluation.
Taking one of your examples below,
find . -print -or -prune -name dir1
this is grouped as
find . -print -or \( -prune -and -name dir1 \)
find will then evaluate the whole expression from left to right for each
pathname in the tree it's looking at, stopping within each set of (implied)
parentheses and within the overall expression as soon as it can determine
truth or falsehood. (This is what's referred to in programming as
short-circuiting in boolean expressions).
If primaries are linked by -and, find can stop at the first one that's false,
knowing the expression is false; if they're linked by -or it can stop at the
first one that's true, knowing the expression is true. Otherwise it has to
evaluate the whole expression.
Before it does this, though, find checks for side-effects. If there isn't a
side-effect anywhere in your expression, find will put brackets round the
whole expression and a -print after it.
Looking at your examples:
chr...@pcbsd% find .
(No expression). Find adds a -print, so this is the same as the next one:
chr...@pcbsd% find . -print
.
./test.mov
./test.mpg
./dir1
./dir1/file1
./dir1/file2
./file3
-print is always true so the expression is true for each name - they get
printed as a side-effect.
chr...@pcbsd% find . -print -o -prune dir1
find: dir1: unknown option
-prune doesn't take an argument, so dir1 is a syntax error.
chr...@pcbsd% find . -print -o -prune -name dir1
find evaluates the print, which prints each name as its side-effect. -print
evaluates as true. Since it's in an -or, find can stop there, so it never
sees the second expression ( -prune -and -name dir1: the -and is implicit).
.
./test.mov
./test.mpg
./dir1
./dir1/file1
./dir1/file2
./file3
chr...@pcbsd% find . -print -o -name dir1 -prune
Same again: find stops after the -print which is always true, and ignores
the -name dir1 -and -prune.
chr...@pcbsd% find . -name * -o -name dir1 -prune
None of these primaries has a side-effect, so find rewrites this internally as
find . \( -name * -or -name dir1 -prune \) -print
-name * is always true, so find can ignore everything after the -or up to
the parenthesis. Because the first expression is true, and the parens are
followed by (an implied) -and, find has to evaluate the -print, which is
always true, so the whole expression is always true and it always prints the
name as a side-effect.
.
./test.mov
./test.mpg
./dir1
./dir1/file1
./dir1/file2
./file3
What you need is an expression with two outcomes: a -prune for some names and
a -print for others. That tells you you need an -or, and the -print must come
after it because it's always true. Before the -or, -prune is always true so
you need some sort of testing primary before the -prune.
That gives you
find . -name dir1 -prune -or -print

When it's false it only evaluates its left-hand argument; when it's true it only evaluates its right-hand argument; and whenever the argument it's currently looking at returns true, the expression changes state. If the argument is an integer, it's treated as a comparison against the current line number, $. ; so the first expression, 8..10, means ($. == 8) .. ($. == 10) It's false to start with, until ($. == 8) returns true (on line 8); it becomes true and remains true until ($. == 10) returns true (on line 10), when it becomes false again and remains false until it next sees line number 8. You can also use more complicated tests in the range operator: perl -ne 'print unless /START/ .. /END/' will find each line containing the word START anywhere, and delete from that line to the next line containing END (inclusive of both endpoints) - this will work for multiple occurrences of START and END in your file. There are two problems if you string multiple files together on the command line: first, if you're using line numbers, the line number doesn't reset between files unless you do an explicit close on each file. The bigger problem is if you have a file in which the second condition doesn't occur (a file with only 9 lines in the first example, or a file with a START and no corresponding END in the second case): the range operator will stay true until it sees the ending condition in the next file, meaning you'll lose the first ten lines in the numeric case, or every line from the top of file to the first END in the second case. To get round these two problems, you need to test for eof in the range operator, and close each file when it hits eof to reset the line count. perl -ne 'print unless 8 .. $. == 10 || eof; close ARGV if eof' file[1-n] perl -ne 'print unless /START/../END/ || eof; close ARGV if eof' file[1-n] There's some hairy precedence in the first range expression: a useful tip for checking that you've got it right (and indeed in general for checking that a bit of Perl does what you think it does) is the B::Deparse core module, which you call like this: perl -MO=Deparse,-p -e 'print unless 8 .. $. == 10 || eof' which outputs ((8 .. (($. == 10) || eof)) or print($_)); -e syntax OK The ,-p argument to -MO=Deparse tells it to put in parentheses everywhere. If you're like me and like to leave them all out, feed your expression to Deparse with all the parens in and leave off the ,-p argument: Deparse will get rid of all the unnecessary ones: $ perl -MO=Deparse -e 'print unless (8 .. (($. == 10) or eof))' print $_ unless 8 .. $. == 10 || eof; -e syntax OK Jonathan ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Give me a break. The OpenBSD team of volunteers makes a new release every six months, with target release dates in May and November. I can't recall a slip of even one day. I know, this isn't OpenBSD, but it proves that a regular release schedule is indeed possible. also remember that 6.4 was being worked on at the same time. there's only a finite number of people to spread across both projects. finalization of 7.1 should come faster as 6.4 has been released According to http://www.freebsd.org/releases/7.1R/schedule.html , the ports tree was frozen on 8 September, tagged on 22 September and unfrozen. (I see elsewhere in this thread someone saying it's still frozen - I'm not sure which statement is correct). 7.1-RELEASE should have been done a couple of weeks later - early in October for announcement on 13 October. We are now looking at a release in January. That's not a few days or even a few weeks late - it's almost four months late; and 7.1-RELEASE will ship with a ports tree that's almost 5 months out of date. Not only that - it's shipping mere weeks before the end-of-life for 7.0-RELEASE (currently 28 Feb 2009). I have been watching the web page and freebsd-stable. There has been no obvious indication of the reason for the delays or the expected duration. (For earlier releases, there was a todo page linked from the release webpage which listed areas needing more work and areas needing testing). The -RC1 release announcement finally acknowledged that there had been a number of major problems, not all of which have been fully addressed yet. As a community, we should be ashamed of this: ``volunteer effort'' just isn't a good enough excuse - and those of us who haven't volunteered need to find out how we can help get things back on track for the next release. When I first raised this, I asked if there was anything I could do to help the release engineering team with communication. Zbigniew Szalbot made a similar offer. I really think that once 7.1 is out, we (collectively) need to have a long hard look at the release process and make sure this doesn't happen again (and again and again and again - it's not the first time that I've scheduled work around release dates and ended up being embarrassed or having to do jobs twice, with a pre-release and then again when the release arrives.)

I have a feeling that Internet Explorer ignores the Content-Type header from the server and displays what it thinks you should see. If the server is not configured with a MIME type for .php, the default with Apache is to send the pages with a MIME type of text/plain. Internet Explorer will ignore this, interpret the page as HTML and display it, whereas almost every other browser will obey the server's instruction and therefore display the raw HTML as plain text without any interpretation. Check whether Apache has an AddType application/x-httpd-php .php line or similar in the config file.

Release schedules
I've been biting my tongue about this because I'm not sure that I can offer any help or useful suggestions, but here goes... What on earth is going on with release scheduling? FreeBSD 7.1-RELEASE, according to the scheduling page at www.freebsd.org, should have had a Release Candidate published two months ago, on 13 September. Instead we're still on a Beta - BETA-2, which isn't mentioned in the original schedule. The todo list which has appeared on the website in previous releases isn't available this time, so I can't even get a feel for the likely cause of the holdup. As I said, I hate to stand on the sidelines and heckle when I'm not doing anything to contribute to the release, but the timetable has slipped badly and I don't feel I can find information about the reasons or the revised timings. What exactly is going on, and is there anything a busy sysadmin, poor in time, bandwidth and C skills, can do to help with either the release itself or the apparent scheduling/communication issues? (I've sent this to -questions rather than -stable because it seems to be an ongoing problem with the timetabling of releases.)

Look under parameter expansion in the manpage for sh(1) (or bash(1) if you

Essentially, a Bourne-type shell with parameter expansion expands
${variable#prefix} or ${variable%suffix} to $variable with the prefix or
