I jumped on sets for that, putting everything in sets and checking the world file occasionally so that if there's anything it it at all, it's either because I put it there specifically as a package purgatory, or because I forgot... but evidently I've used my scripts so consistently that I've never forgotten., as I've yet to find anything there I didn't deliberately put in package purgatory. Actually, I ended up using sets back when I setup my netbook, as I needed some way to sort thru the main machine's world file and figure out what listings I wanted for the netbook and which not, and I was familiar with the then new sets feature from the kde overlay, and decided sets were the perfect way to category-sort everything, figuring out what I wanted on the netbook at the same time. I don't update the netbook anything even close to as consistently, however, often ending up going a year or even two between updates (security isn't a big issue as I deliberately keep anything sensitive off the netbook already, and use it more offline than as as a NETbook in any case), but because I keep the sets identical except for #-commenting a package here or there on one side or the other, when I /do/ update it's a relatively simple matter to diff the sets along with the use file (separate and sourced from make.conf) and package.* files, updating the netbook's files based on the main machine's files as I go. Then it's mostly a matter of iteratively updating what can be updated, skipping what can't as the jump is too large and other packages need updated first, dealing with the problems one at a time, until everything updated and I can once again do an emerge empty-tree world without issue. -- Duncan - List replies preferred.

[gentoo-dev] friendly reminder wrt net virtual in init scripts
All, I would like to remind everyone about the tracker for services that are misusing "need net" in their OpenRC init scripts [1]. "need net" should be removed from our init scripts, because it is bogus and breaks things. I also question the value of "use net", because the same thinking applies, e.g. the net virtual really doesn't have a strong meaning of any kind. For more details, see the tracker and flameeyes' blog post. Thanks, William [1] https://bugs.gentoo.org/show_bug.cgi?id=439092 signature.asc Description: Digital signature

The last time I brought it up was in, https://bugs.gentoo.org/show_bug.cgi?id=397313 but you can chase the bug trail back to 2004. There are plenty of people on both sides. I haven't changed my mind, but the problem is "solved" here. I spend hours writing metapackages for the things that I want recorded in @world so that they can be differentiated from the things that were --updated without --oneshot (which is easy to forget). The servers that were alive during the silent changes in behavior were physically retired.

Cool story bro. Such "nonsense" puts me in good company, given "nonsense" such as "mv" "cp" and "rm", in the best Unix tradition! So thanks for the compliment! =:^) Just as beginner Unix admins /think/ "move" when they type mv, until mv becomes its own concept and thinking "move" is the long way around, I /thought/ "emerge ask world" when I typed eaw, until familiarity made eaw the normal concept, and "emerge --ask (-NuDv) @world" became the long way around I seldom gave much thought to any longer. As for tab-completion, it only takes a bit of shell-script to add the tab- completion already available for emerge, to my ea*/ep* variants as well, and they're tab-completed with (other) options and package names exactly as if I had typed/completed out the longer form. Drop that in the same autocomplete location and I'm good to go! =:^) Nobody says you have to use it, and I was in fact arguing that everybody develops their own such shortcuts over time. My solution's not for everybody and apparently not for you, but that's fine, because it's uniquely custom designed for me! =:^) But what makes Unix/Linux/Gentoo great is that this same level of unique custom design is available and exposed to everyone, for their own use as they see fit. =:^) -- Duncan - List replies preferred.

I imagine were emerge being written today, -1 /would/ be the default, and there'd be an option like --select to add to the @world file if necessary. That's actually the way I setup my scripts, with -1 the default, and an extra "2" suffix script variant that did add to the world file.

Again, if it were available (and something I knew about) back in the day... I might have ended up with that. However, I've come to appreciate an advantage to writing one's own scripts -- bug fixing or adding new functionality is a *LOT* easier since you're already familiar with the code. In fact, speaking from experience, adding support for a new feature to a script you've created yourself is often easier than figuring out the new config options for the same feature for an upstream script, when they add support for it! Plus, you don't have to worry about learning new config options for new features you'll never use, since you simply don't code them in the first place. =:^) The ebuild-patching tree and auto-redigest features were in fact recent adds, when I needed something that scaled better than one-off ebuild editing during the time gentoo/kde dropped support for USE=semantic- desktop and I had to carry my own patches to kill it. (FWIW, they've since reverted and offer USE=semantic-desktop again now, THANKS gentoo/kde! =:^) Similarly, adding git functionality to my existing kernel scripts wasn't difficult, and arguably easier to do since I knew the code, than trying to reverse engineer the new config options and perhaps the supporting code behind it, were I using an upstream solution that added git kernel support to existing helper scripts. >> I have a similar set, but starting with k* instead of e*, for automatic >> mainline kernel fetching, building, etc. > > This is rather cumbersome, since you should have different permissions > for building and installing (if you use the recommended way to build > into a separate KBUILD_OUTPUT with e.g. portage permissions). > Except for fetching, you might want to use the kernel script from the mv > overlay. Actually, both different building/installing permissions (via config file sudo option, tho I'll admit since I set that the option, running with that option turned off isn't tested, but the basic script infrastructure for it is there), and KBUILD_OUTPUT (setting in the config file) are already supported. =:^) And talk about ease of adding functionality, when I setup my 32-bit netbook build chroot, it was just a few lines changed in the kernel scripts themselves, and a "dynamic config" line added to the config file (which is sourced, so accepts both var=val style and dynamic config script snippets) to auto-detect which system I was building for and set KBUILD_OUTPUT accordingly, thereby keeping the work dirs and config entirely separate, automatically, via "dynamic config". Trivial feature-add, and now that it's there, if I suddenly needed to scale to 100 or 1000 different kernel configs, that'd be even more trivial (even just a config file change), if necessary by having the config file source yet another "separate-builds.conf" file with its own dynamic-config logic to choose between the different configs. This sort of solidly sysadmin level helper/glue script is something Unix/ Linux/Gentoo is well optimized to make not only possible, but trivial, to implement, and I definitely put that feature to use! =:^) -- Duncan - List replies preferred.

The -v option is already in my make.conf file for portage but I do type it in out of habit sometimes. I do sometimes add -t if I think it will help. Sometimes it does, sometimes it doesn't. My point still remains, emerge -uaDN world has given me the most stable system so far.

Duncan, Alan, Neil and others are MUCH more experienced than I am on the code part. So, if I need something fixed, emerge -e world may be the only option.

What do you consider a stable update process? I consider it stable when things work as they should except for known bugs upstream. Obviously if there is a known bug upstream then that bug will likely filter right on through to Gentoo.

It does require prior knowledge which is why I said what I did. I used to do emerge -u world way back when. That would SOMETIMES lead to issues because it may not go deep enough. Then I added -D which helped but from time to time would still miss something. So, I added the backtrack to make.conf. That improved things even more. Over time, I realized that I needed to add the -N option so it got added to the command. As it is now, I have that knowledge. I learned some of that the hard way. You are right, it does require prior knowledge and as a user gets that knowledge, they likely end up where Alan, Duncan and myself are. That would be emerge -uaDN world. Right now, that has lead me to the most stable OS. When it doesn't, I do a emerge -e world if nothing else fixes the issue. That doesn't happen as much as it used to because either Zac is tweaking portage or devs are doing better on the ebuilds. Heck, it could be both since both need to work well to get a good end result. > >> The only way to get a more stable system is to do a emerge -e world >> and update that way.

I would run into a problem and recompiling the obvious packages didn't correct the issue. Doing a emerge -e world would fix the issue. Obviously something fell through the cracks that my usual command would miss but the -e would catch since it does all packages. I never reported the issue since I don't know what specifically fixed the issue. There is no way for a person to figure out if it is a portage issue, ebuild issue or some other issue. I didn't see the point in filing a bug because there is no way to track down the source of the problem. This is my experience. By all means, if you do something different and it works for you, do it your way. I'm going to continue doing what works for me. If someone asks me how I do things, I'll recommend the same command/settings I use just like I'm sure some other old timers will do. Dale :-) :-) -- I am only responsible for what I said ...

I would love to see a simple way to invoke emerge such that it just "does the right thing" in updating the system. Its behavior would always be considered subject to change (scripts should use the long options if they don't just want the latest automagic behavior). I see this as having several benefits: 1. It is newbie friendly. Anybody can understand apt-get update, apt-get upgrade. If I told you what I invoked to do my daily updates on Gentoo it would start a religious war on whether I'm doing it right. 2. It is supportable. If a developer pushes out a commit without a news item such that a stable user runs the standard update command before the commit and after it and the second update fails, then that is a valid bug. I'm not suggesting that all such bugs are preventable/etc, but it does help get rid of the whole "you're holding it wrong" debate. 3. It is maintainable. When new portage features arise they can be added to the default behavior when appropriate, without the need to get everybody to change their command lines. 4. It is a standard. Gentoo is all about being able to deviate from the standards. However, there is still value in suggesting a best practice. Rich

Heh, seems the ML overwrote my Reply-To header (infra bug? it is correct in Sent); as we're not supposed to be discussing this here. Yeah, I've asked about "pulled in by (no parents that aren't satisfied by other packages in this slot)" on #gentoo-portage and it is a weird state in the backtrack code; it was said by dwfreed there to intentionally not remove the orphans until it finds a solution, since it doesn't find one it outputs them.

What do you consider a stable update process? I come across users on a daily basis which - haven't upgraded their system lately because they're not good at it; - get into unclear slot conflicts locking them out of updates; - some build failure disallows their dependency graph from completing; - managed to finally update, but don't know about depclean; - managed to finally depclean, but don't know about eclean. It involves a lot of prior knowledge, manual checking and what in order to be able to update the system; I wouldn't label this "stable", but rather "dependent on the person updating it" and to some extent even "dependent on whether the person memorized all the docs and/or gets helped or get it told in the support channels". There are some improvements possible in these situations; I'm planning to discuss some ideas and write some patches where possible, and I hope other people jump on the bandwagon to help improve user experience.

Cool story guys.
Just like how MSOffice 2007 had tons of shortcuts to remember whereas
they got rid of that in MSOffice 2010 by intuitive context relevant
shortcuts; yet, people had memorized the shortcuts and are much quicker
than having to learn all the positions in the new intuitive Ribbon bar.
I didn't learn those shortcuts; so, I am quick with the Ribbon bar...
Or why do
ebuild name-1.ebuild clean manifest unpack
ebuild name-2.ebuild clean manifest unpack
diff -urN /var/tmp/portage/name-{1,2}/workdir/*
# ^ Actually, you would need to source S="..." twice.
which requires a ton of tabs when I can just do `ediff 1 2`? I can
memorize it, but perhaps others need more short commands and can't.
You'll find out that people end up using both approaches; so, please
let's not get into detailed opinions, it is just a matter of choice.

They also figure out what defaults to add to make.conf as well. For that, it is as Duncan and Alan describe. Both have been using Gentoo for quite a while. I been using Gentoo for a good ten years. I installed from Gentoo 1.4 I think. Here is mine in make.conf: EMERGE_DEFAULT_OPTS="--with-bdeps y --backtrack=30 --keep-going -v -j10 --quiet-build=n -1" For my updates, I use this: emerge -uaDN world The only way to get a more stable system is to do a emerge -e world and update that way.

Yeah, we do...
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1#doc_chap3_sect5
So, we're not really trying to solve a problem here; yet we can improve
the situation so people don't have to manually retype the same chain of
commands everytime or rewrite their own shell alias or function.

Yeah, I think everyone has implemented their own kind of alternative:
eupdate()
{
emerge -uDN @system @world
dispatch-conf
etc-update
emerge -uDN @system @world
emerge -c && (
eclean-dist -d
eclean-pkg -d
emerge @preserved-rebuild
)
}
Others have worked together and put it into a handy tool:
http://weaver.gentooexperimental.org/update.html
It would indeed be nice to join efforts and have something that does to
updating what genkernel does to kernels, then get that into the
Portage tree and suggest it as an alternative to doing it manually.

Yes, there is describes what are possible ways to update the system and what criteria goes into selection of the packages to update but not which one is recommended, generaly for regular update. Could be helpful for newbs and to avoid doubt even between more experienced users. I think only -u world could be used to do updates.

The following keyword changes are necessary to proceed: (see "package.accept_keywords" in the portage(5) man page for more details) # required by dev-python/PyQt4-4.10.2 # required by kde-misc/synaptiks-0.8.1-r4 # required by @kde_sed # required by @selected # required by @world (argument) =dev-lang/python-exec-0. ** = PyQt4 and synaptiks were only the messengers, btw. dev-lang/python-exec-0. has the Targets pypy2_0 and python3_3 which dev- lang/python-exec-0.3.1 does not have. But both dev-python/python-exec-1.1 and dev-python/python-exec-1.2 want a dev-lang/python-exec:0 with the same target setting. Btw. Why does dev-python/python-exec:2 has a dependency on dev-python/python- exec:0 ? Cheers Sven signature.asc Description: This is a digitally signed message part.

Given the power and flexibility of portage/emerge and the extremely broad variety of needs that Gentoo meets, I believe it would be somewhat wasted work to add the option when users are already expected to read manpages and the Handbook. Perhaps -avuND should be made more obvious in a place or two in the documentation as a sort of compromise.
