[arch-general] Dependency Hell
by Chris Tonkinson 15 Jul '14

15 Jul '14

Hi all, I have ZFS (from AUR) and VirtualBox (from Community) installed. The problem is that these both dependend typically on very specific kernel versions, and usually ("usually" being a subjective and ill-defined term slanted by when and how often I update my system; at least once per day) cause dependency failures which prevent *ANY* upgrades from being processed. As such, my /etc/pacman.conf contains an ignore declaration: IgnorePkg = linux zfs-git spl-git virtualbox virtualbox-host-dkms virtualbox-host-modules So once in a while, I'll comment out my IgnorePkg and attempt a system update and expect it to fail because getting the kernel, ZFS, and VirtualBox all to line up at the same time feels like, to quote Scotty, "trying to hit a bullet with a smaller bullet, whilst wearing a blindfold, riding a horse." Is there any graceful solution here? Clearly the three won't (can't) ALL be bleeding edge simultaneously, but is there a sane workaround to keep them as-current-as-possible without pacman barfing on everything else. It's not immediately obvious to me how to combine IgnorePkg, HoldPkg, and NoUpgrade to achieve the desired result.

[arch-general] Error installing linux-3.15.5-1
by Thorsten Jolitz 11 Jul '14

11 Jul '14

Hi List, just did my usual pacman -Syu and was offered a new linux version, which I accepted to install, but got 1000s of error messages like this: ,---- | linux: /usr/lib/modules/3.15.5-1-ARCH/modules.symbols.bin exists in | filesystem | linux: /usr/lib/modules/extramodules-3.15-ARCH/version exists | in filesystem `---- A few hours before pacman complained that the DB is locked, and I removed the db-lock (as proposed) since I was sure I had no pacman operation going on. Do I have a corrupted pacman DB now? What would be the steps for diagnosis and repair? -- cheers, Thorsten

[arch-general] pypy3 to pypy
by Charles Joachim 11 Jul '14

11 Jul '14

Hi, I'm really interested in Pypy and starting to use it daily but I mainly prefer the use of Python 3 in general. With the announcement of the first stable release of Pypy3, I would like to know what do people think of switching: pypy -> pypy2 pypy3 -> pypy Like that, it would be in sync with the name change of Cpython. What do you think?

[arch-general] Gummiboot and EFISTUB booting irregularities
by Murari 11 Jul '14

11 Jul '14

Hi all, I couldn't find a better way of phrasing this as I'm not quite sure what the problem is or how to debug this. I have Arch with the 3.15.1-1 kernel installed on an HP laptop (intel motherboard), booting using gummiboot and the EFISTUB loader. When I start my laptop (or restart it) and select the Arch Linux entry in the gummiboot menu, I sometimes only see a blank screen instead of any error messages or any of the usual boot text. Ctrl+Alt+Del reboots my laptop. Seemingly at random, if I try again at this point, Arch sometimes boots and sometimes doesn't. Journalctl does not list any entries at all for the failed boot attempts. Can anyone suggest any ways of debugging/solving this? Thanks!

[arch-general] ZFS, dm-crypt, and systemd
by Chris Tonkinson 10 Jul '14

10 Jul '14

Can anyone provide a reference to documentation on how to configure systemd to mount all dm-crypt devices in /etc/crypttab prior to importing ZFS pools on boot? (zfs-git, not zfs-fuse) Thanks! -Chris -- Chris Tonkinson 610.425.7807 "Lead, follow, or get out of the way." -Thomas Paine

[arch-general] misconfigured systemd dependencies
by Chris Tonkinson 09 Jul '14

09 Jul '14

Hello, I have a LUKS drive (called "locker-1"), which is necessary to be properly mounted before ZFS can import my pool on boot. I believe systemd needs to be explicitly configured to mount dm-crypt devices before doing anything ZFS-related, but I'm relatively new to working with systemd so I'm stuck on the implementation. I believe the following is revelant configuration information: ~ $ systemctl list-units | grep "crypt\|zfs" systemd-cryptsetup(a)locker\x2d1.service loaded active exited ... zfs-import-cache.service loaded active exited ... zfs-mount.service loaded active exited ... zfs-share.service loaded active exited ... system-systemd\x2dcryptsetup.slice loaded active active ... cryptsetup.target loaded active active ... zfs.target loaded active active ... ~ $ find /usr/lib/systemd/ -name *crypt* /usr/lib/systemd/system-generators/systemd-cryptsetup-generator /usr/lib/systemd/systemd-cryptsetup /usr/lib/systemd/system/cryptsetup.target /usr/lib/systemd/system/sysinit.target.wants/cryptsetup.target ~ $ find /usr/lib/systemd/ -name *zfs* /usr/lib/systemd/system-preset/50-zfs.preset /usr/lib/systemd/system/zfs.target /usr/lib/systemd/system/zfs-share.service /usr/lib/systemd/system/zfs-import-cache.service /usr/lib/systemd/system/zfs-import-scan.service /usr/lib/systemd/system/zfs-mount.service Based on my limited understanding of systemd dependency resolution from [1], I created a custom file to force ZFS to depend on my LUKS device: ~ $ cat /etc/systemd/system/zfs-import-cache.service.d/luks.conf [Unit] Requires=systemd-cryptsetup(a)locker\x2d1.service After=systemd-cryptsetup(a)locker\x2d1.service I rebooted and no joy, though `systemd-delta` does see the override: ~ $ systemd-delta [EXTENDED] /run/systemd/system/session-c2.scope → /run/systemd/system/session-c2.scope.d/90-SendSIGHUP.conf [EXTENDED] /run/systemd/system/session-c2.scope → /run/systemd/system/session-c2.scope.d/90-After-systemd-user-sessions\x2eservic [EXTENDED] /run/systemd/system/session-c2.scope → /run/systemd/system/session-c2.scope.d/90-After-systemd-logind\x2eservice.conf [EXTENDED] /run/systemd/system/session-c2.scope → /run/systemd/system/session-c2.scope.d/90-Description.conf [EXTENDED] /run/systemd/system/session-c2.scope → /run/systemd/system/session-c2.scope.d/90-Slice.conf [EXTENDED] /usr/lib/systemd/system/zfs-import-cache.service → /etc/systemd/system/zfs-import-cache.service.d/luks.conf Looking back, I notice that ZFS has definitions for both importing via cache or scan, so I duplicated this override for `zfs-import-scan.service` and get the same result. Oddly (to me), the boot log shows ZFS inner workings, but nothing about dm-crypt: ~ $ journalctl -b | grep 'zed\[' Jul 09 05:20:03 vigilance.thetonk.net zed[720]: ZFS Event Daemon 0.6.3-1 Jul 09 05:20:03 vigilance.thetonk.net zed[720]: Processing events since eid=0 Jul 09 05:20:03 vigilance.thetonk.net zed[720]: Invoking "all-syslog.sh" eid=1 pid=726 Jul 09 05:20:03 vigilance.thetonk.net zed[727]: eid=1 class=statechange Jul 09 05:20:03 vigilance.thetonk.net zed[720]: Finished "all-syslog.sh" eid=1 pid=726 exit=0 Jul 09 05:20:03 vigilance.thetonk.net zed[720]: Invoking "all-syslog.sh" eid=2 pid=729 ... ~ $ journalctl -b | grep 'crypt' ~ $ Any advice would be greatly appreciated. For what it's worth, this is just the first drive of six (I'm in the process of encrypting my RAID-Z2 pool in-place) so the DRYest-configuration solution is optimal but at this point I'll take what I can get. [1]: https://wiki.archlinux.org/index.php/Systemd#Editing_provided_unit_files Cheers, -Chris PS: The only thing that sticks out at me visually at this point is that "\x2d" in places; is the inclusion of a hyphen in my LUKS device name causing problems? It seems like systemd sometimes? does magic with hyphens and paths, which is why I assume it's being encoded but I figure I would ask. -- Chris Tonkinson 610.425.7807 "Lead, follow, or get out of the way." -Thomas Paine

Because, while we're at it... I'm not very proud to add, don't use sudo while moving around /etc/group. I'm currently travelling and more or less only have this machine to work with. As I haven't memorized any systemd boot flags, some time later I finally found a way to get back up and running by setting "init=/bin/bash"... So, really, don't use sudo for /etc/{passwd,shadow,group,gshadow}. cheers! mar77i
