What about to extend the pkg_delete to use a syntax like :

If you install packages A, B and C at the same time and A depends on C, it's not smart enough to install C first. pkg_order | tsort should do the job, one would presume. 2. It does an even more terrible job at fetching dependencies. Try installing a complex set of programs and files (e.g. gnome) and see how many individual components you have to fetch. Contrast with "cd /usr/ports/x11/gnome; make install". Both of those are handled by the apt-get program, and were in the past handled by dselect (but dselect is horrid for a whole load of other reasons). apt-get does a better job at collections, true, but in my experience still does not do a proper package ordering before installation. And if component packages have inconsistent dependencies, apt-get puts your system in a state that is hard to recover from. I've had both of these things happen to me while installing gnome. Now one can argue that this reflects a problem with the individual package rather than the infrastructure, but I feel that if a package manager deals with a bundle in a manner similar to a package, it should deal with consistency issues of the component packages. Don't get me wrong. I think that the problem that Debian package manager is trying to solve is not an easy one to solve in a completely bulletproof manner and I don't have a solution to offer offhand, either. apt-get is undoubtedly an improvement on dselect, but I think it builds on a fundamentally shaky infrastructure, IMHO. My gut feeling is that one would be better off building a super-duper package management system on top of the ports mechanism and extending the existing pkg_* tools.

What if chroot itself chdir'ed to it's new root directory? Would this break existing programs? I'd expect that well-behaved programs would chdir someplace useful before continuing anyway. At the very end of chroot(), could it just vrele(fdp-fd_cdir); fdp-fd_cdir = nd.ni_vp; before it returns, setting the current dir to the same place it just chrooted to?

Re: A new package fetching utility, pkg_get

While we're talking about making package handling easier for
newbies, I'd like to present two simple shell scripts that I

but I'm not sure if they're really worth it (if someone thinks
they are, then I'll send-pr them).
Here's a bit of me-too-erism, and (I hope) some food for thought
and discussion:
I've longed for a mechanism to keep the ports that I use as
up-to-date as the rest of my FreeBSD system. Unfortunately,
some ports I don't use very often, and so forget that they're
there.
Unfortunately (again), the port name-version_number identifier
isn't _quite_ unique enough to use as a key for tracking ports.
For example: ssh and docbook have multiple versions for the same
base name installed concurrently.
What I'd like is a little weekly crontab script that runs after
my weekly ports cvsup, and tells me which of the ports that I
"subscribe to" has changed, so that I can think about rebuilding it.
This is the closest I've come, so far. Comments and suggestions
welcome, of course:
pkg_info -a -q -I tags
pkg_info -a -I | awk '{print $1}' | paste -d\| - tags | sort
-t\| -k 2 alist
sort -t\| -k 4 /usr/ports/INDEX |\
join -t\| -o1.1,2.1 -1 2 -2 4 alist - |\
awk -F\| '{if ($1 != $2) print $1 "--" $2}'
This throws up some obvious candidates, like:
mutt-1.0b1--mutt-1.0b2
But also some dubious ones:
bzip2-0.9.0c--bzip-0.21
bzip2-0.9.0c--bzip2-0.9.5c
And some that seem to have different pkg_* names from the values
in the INDEX file:
squid-2.2--squid-2.0
squid-2.2--squid-2.1
This probably also loses for any ports where the comment field
has changed...
I've thought about parsing the "updated ports" list that gets
posted to usenet every (?) month or so, but that seems hard too.

Re: 3.3-R on Dell w/ DPT RAID
I've pored over -question, to no avail, so here goes. We are trying to install FreeBSD 3.3-RELEASE on a Dell PowerEdge 6300. Said beast has a DPT SmartRAID IV controller, and 2G of memory. We've told this machine via it's BIOS to pretend it only has 256M. When we try an install from the floppies, the mfsroot floppies panics with an 'pmap_enter: invalid page directory, pdir=0x601063, va=0xc240'. I have no idea what this error message means. It suggests that you have memory problems; have you tried physically extracting most of the memory from the system? -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ [EMAIL PROTECTED] \\-- Joseph Merrick \\ [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Re: mrtg,FreeBSD, asus p2b temperature
MRTG is capable of graphing anything that can be expressed as a number. For an example look at the contributed example that graphs estimated bandwidth. I modified this to run with nttcp and use it to track the capability of all my circuits. Someone has a method of monitoring temperatures via a probe at a reasonable cost and inputting it to the computer but I don't remember where I saw it.

The mainboards of the ASUS P2B series have everything onboard that you need.

However, the problem is, it only works with 3.0-current from around January. It doesn't work with any recent -stable or -current. I suspected it was because of newbus, so I tried to port it, but without success. :-( Regards Oliver -- Oliver Fromme, Leibnizstr. 18/61, 38678 Clausthal, Germany (Info: finger userinfo:[EMAIL PROTECTED]) "In jedem Stück Kohle wartet ein Diamant auf seine Geburt" (Terry Pratchett) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
