[arch-general] makepkgchroot
by Myra Nelson 18 Jun '11

18 Jun '11

I'm attempting to set up a clean chroot to build packages in. I've followed the instructions on the wiki page https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chro…. I've read all the posts on the forum, than man pages, and the mailing lists (I may have missed something) and haven't found any answer to my problem; Steps to recreate: 1. sudo mkarchroot ~/chroot/root base base-devel sudo -- success 2. edit pacman.conf, makepkg.conf, and mirrorlist in the chroot directory 3. sudo mkarchroot -u ~/chroot/root -- success 4. a) [myra@gandalf ../repos/core-x86_64]:sudo makechrootpkg -c -r ~/chroot creating clean working copy...done /usr/sbin/makechrootpkg: line 194: /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory /usr/sbin/makechrootpkg: line 199: /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory sed: can't read /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory /usr/sbin/makechrootpkg: line 204: /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory sed: can't read /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory /usr/sbin/makechrootpkg: line 209: /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory grep: /home/myra/chroot/myra/etc/makepkg.conf: No such file or directory /usr/sbin/makechrootpkg: line 244: /home/myra/chroot/myra/etc/sudoers.d/nobody-pacman: No such file or directory chmod: cannot access `/home/myra/chroot/myra/etc/sudoers.d/nobody-pacman': No such file or directory error: '/home/myra/chroot/myra' does not appear to be a Arch chroot please build the image using mkarchroot Build failed, check /home/myra/chroot/myra/build b) [myra@gandalf ../repos/core-x86_64]:sudo makechrootpkg -r ~/chroot/root Missing chroot dir root directory. Try using: mkarchroot /home/myra/chroot/root/root base base-devel sudo usage makechrootpkg [options] -r <chrootdir> [--] [makepkg args] Run this script in a PKGBUILD dir to build a package inside a clean chroot. All unrecognized arguments passed to this script will be passed to makepkg. The chroot dir consists of the following directories: <chrootdir>/{root, copy} but only "root" is required by default. The working copy will be created as needed The chroot "root" directory must be created via the following command: mkarchroot <chrootdir>/root base base-devel sudo Default makepkg args: -s --noconfirm Flags: -h This help -c Clean the chroot before building -u Update the working copy of the chroot before building This is useful for rebuilds without dirtying the pristine chroot -d Add the package to a local db at /repo after building -r <dir> The chroot dir to use -I <pkg> Install a package into the working copy of the chroot -l <copy> The directory to use as the working copy of the chroot Useful for maintaining multiple copies. Default: myra Using [myra@gandalf ../repos/core-x86_64]:sudo makechrootpkg -r ~/chroot/myra gets the same results as b). I don't think anything is wrong with makechrootpkg. I'm sure it's something simple and I'm probably just brickheaded and can't sort out what I'm doing wrong. If someone has a two by four to hit me with and straighten out my thinking please don't hesitate. Myra -- Life's fun when your sick and psychotic!

[arch-general] On module blacklisting
by Magnus Therning 18 Jun '11

18 Jun '11

I just read about the changes to module blacklisting[1] and I'm left wondering: 1. As I read it, it's only blacklisting that's affected, is that correct? So MODULES in rc.conf can in the future only be used to load modules at boot-up. (Is there even a way to configure modprobe to load modules on boot?) 2. When does this change take effect? Which version of which package will it come with? /M [1] http://www.archlinux.org/news/changes-to-module-blacklisting/ -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus I invented the term Object-Oriented, and I can tell you I did not have C++ in mind. -- Alan Kay

[arch-general] Why are install functions not in PKGBUILD?
by Matthew Monaco 16 Jun '11

16 Jun '11

It seems like the install functions pre/post_install/upgrade/remove could be defined right in the PKGBUILD. Any particular reason why this isn't or cannot be so?

[arch-general] makechrootpkg -I (any way to pass --noconfirm ?)
by David C. Rankin 16 Jun '11

16 Jun '11

Guys When installing packages into an archroot with the '-I' option to makechrootpkg is there any way to also pass the '--noconfirm' option to pacman? I have tried a couple of different ways to pass it after the -I option, but so far it is a no go. I'm trying to automate the trinity build in an archroot, but having to confirm each install after the module build is preventing this. What say the experts? -- David C. Rankin, J.D.,P.E.

[arch-general] TeXLive 2011 pretest
by Rémy Oudompheng 15 Jun '11

15 Jun '11

TeXLive 2011 is in pre-testing phase. Experimental builds of texlive-bin will be found in http://pkgbuild.com/~remy/texlive-experimental/ Current issues are: - no install script for texlive-bin where it should run "mktexlsr" and "fmtutil-sys --all" - dangling symlinks, due to new scripts appearing in texlive-* - segfaulting luatex, so I guess I'll keep with compiling it separately - no biblatex-biber. TeXLive only provide a binary that bundles Perl + all dependencies. I plan to adopt biblatex-biber from AUR for that and add it as an optional dependency of texlive-core. However, it comes with a very unusual set of dependencies. We can only blame François for being a great Perl enthusiast. Once upstream seems stable (they say ConTeXt is currently broken), and the PKGBUILDs reach a final form, packages will hit [testing]. Regards, -- Rémy.

LiveCD beats this any day for me -- i rarely install anything these days because my distro-hopping abruptly ended with Arch :-) (though i do check them out from time to time, or for work related things) -------------------------------------------------- and the end of the day people just want to reinstate a useable system as rapidly as possible. we can yammer on and argue that the user "should not be using testing then", "should be making full backups", "should have/know an alternate recovery plan", "should be manually backing up kernel related stuff", "should be awesomely l33t with linux by now", "prob shouldnt use Arch then" or limitless other assertions, none of which will help anyone learn anything. i can recover my system. i can recover it pretty much no matter how fubificated it is in only a couple minutes because my life is centered around these systems -- to others, if not most, the system is merely a conduit to their own needs/interests, not the focal point. this is important to remember. i think some basic recovery options are a fair request, and one i've seen often enough in various places. if their needs can be made possible by a simple externalized mechanism, and then implemented + maintained by the community, then who is losing? if you don't want it you can simply not use it and your system is no better or worse. in fact, it's not even affected to any degree save some extra checks failing here and there ... you may even find your own use for the triggers. such a mechanism could be used to save packages, save module tree, save images, or anything else one wanted it to do at that critical point. in my own case, i need a way to save the kernel and initramfs before they are replaced -- automatically -- so i can stuff them into a btrfs subvolume for system rollbacks ... i would never ask the user to perform this manually for a million good reasons. the only other option AFAICS is aliasing over the top of pacman. so, while i personally don't care about the threads specific request -- as it will never apply to me -- IMO the motivation is sound, and could be generalized. i propose this threads energy move away from the endlessly debatable focus on "versioning the kernel" to "providing a means to perform custom actions during kernel package transactions, and potentially any package" ... something that maybe everyone can agree on, and something that may prove to enable many new/interesting ideas. so, what sayeth anyone that can make the magic come to life, or anyone else? /etc/pacman/hooks.d/kernel26/<hookname> /etc/pacman/hooks.d/hook.kernel26.<hookname> /etc/kernel26.hook /etc/pacman.linux.hook <whatever> ill be looking into the pacman hooks proposal, but since i cant do C [yet :-] no patches will be from this guy ... external hooks to the .install file is probably pretty simple to implemented even in pacman (then any package could be hooked), but could easily be done in the .install file itself for certain packages, eg. kernel26.
