It has to be something that simple. However, checking, I have booted with the i686 install medium. The box is an older dell P4, so the i686 is correct and matches the system installed. The install disk /bin/bash date is May 7, 2011. The /bin/bash on /dev/sda6 at /mnt/usr/bin/bash (after mount of the system / at /mnt) is January 26, 2013. Attempting the chroot again on fresh reboot gives the same failure: # cd /mnt # chroot /mnt chroot: failed to run command `/bin/bash`: No such file or directory For some reason it is like the system has no ability to find anything. The install cd is a pre /lib change cd, so that may be the issue. I have downloaded the latest install cd and will try again. Thank you again Ross. Any other suggestions welcomed. -- David C.

[arch-general] Cannot chroot '/bin/bash': No such file or directory
by David C. Rankin 07 Mar '13

07 Mar '13

Guys, Attempting to fix the test box that updating left unable to boot, I cannot chroot to fix the system. I've booted from the install medium and done the normal mount of the existing system under /mnt: mount /dev/sda6 /mnt mount /dev/sda5 /mnt/home mount /dev/sda8 /mnt/boot mount -o bind /dev /mnt/dev mount -t proc none /mnt/proc mount -t sysfs none /mnt/sys All files appear in their proper place under /mnt. However, attempting to create the chroot fails: cd /mnt chroot /mnt /bin/bash chroot: failed to run command '/bin/bash': No such file or directory /bin/bash is in the new location /usr/bin/bash (moved from /bin/bash by the update) with with a proper symlink in /mnt/bin/bash pointing to ../usr/bin/bash This if the first time I've ever had difficulty chrooting a system. I suspect that this is caused by the last update that pulled in systemd which left the system unbootable. Anyone know what could be causing the chroot failure? I've tried explicitly pointing the chroot to ./usr/bin/bash, etc... and tried it without any executable specified. Regardless, I get the same "No such file or directory". Thanks in advance for any help or link you can provide. -- David C. Rankin, J.D.,P.E.

[arch-general] Forced to run fsck manually on unattended system
by edd_smith 07 Mar '13

07 Mar '13

Hi, I run a series of remote boxes running Arch. These boxes are unnattended and are very difficult to access. Due to the nature of their power supply they are often powered down without any warning. A UPS is not an option. I have noticed that over time the boxes are showing file system errors and getting stuck during the boot phase requiring manual intervention (Either press Control-D to continue - resulting in failure or log in to the start up shell using the root password and run fsck manually). I simply answer yes to every prompt from fsck and the errors are resolved, the box reboots and runs fine. I need to be able to force an 'fsck -y' type command at every boot as visiting these boxes manually isn't an option. I have already moved the partitions to ext2 as this seemed to show a mild improvement and also set 0 1 flags in /etc/fstab but still I'm seeing the freezing on boot. First of all should I be re-partitioning my drives to something which can handle these kinds of sudden power outages or removing the swap space or something? Secondly can I have arch run a completely unprompted startup whereby fsck will do its best to repair the system without requiring intervention - for me a blank disk is no worse than a frozen system. Thanks in advance, Edward Smith -- View this message in context: http://archlinux.2023198.n4.nabble.com/Forced-to-run-fsck-manually-on-unatt… Sent from the arch general mailing list archive at Nabble.com.

[arch-general] [wpa_actiond 1.4] slow disconnects
by Leonid Isaev 06 Mar '13

06 Mar '13

Hi, With testing/wpa_actiond-1.4 I am having a minor problem when shutting down net-auto-wireless.service: 'systemctl stop net-auto-wireless.service' pauses for ~10sec before finally disconnecting. Of course, this also occurs on normal system poweroff (which is usually ~5sec). The wifi network is WPA "enterprise" (important entries in wpa_supplicant.conf: key_mgmt=WPA-EAP; eap=PEAP; phase1="peaplabel=0"; phase2="auth=MSCHAPV2"), and piece of daemon.log after the above delay has elapsed: Mar 3 17:08:39 bluemoon systemd[1]: Stopping Automatic netcfg wireless connection service... Mar 3 17:08:39 bluemoon wpa_actiond[380]: Interface 'wlan0' lost connection to network 'lsusecure' Mar 3 17:08:39 bluemoon netcfg-wpa_actiond[9323]: :: university-wifi down [done] Mar 3 17:08:39 bluemoon wpa_actiond[380]: Interface 'wlan0' disconnected from network 'lsusecure' Mar 3 17:08:39 bluemoon wpa_actiond[380]: Terminating wpa_actiond session for interface 'wlan0' This is not related to wpa_supplicant 2.0. In wpa_actiond git tree, there was only 1 essential commit (baed7cae042ceb50507066f2df85b06414ab2176) which led to v1.4, but I'm not sure what exactly causes this. Since wpa_actiond doesn't have a --debug switch, how do I trace the issue? Thanks, -- Leonid Isaev GnuPG key: 0x164B5A6D Fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D

[arch-general] Gotta be a stupid gnome-terminal problem

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, All other terminal emulators work. I have checked--thanks to what little I found on the web that seemed apropos--to be sure that /dev/pts is mounted (it is). But when I run gnome-terminal, I get no prompt and typing in commands does not work. This is a brand new installation, so I can't say it worked before some change. All I know is it doesn't work.

[arch-general] Sound problems
by Frank Zimmermann 04 Mar '13

04 Mar '13

Good evening, I'm having troubles getting sound to work aftereach reboot. I've followed the instructions from the wiki. But after each reboot I need to run alsamixer -> selct the soundcard by pressing F6 -> and then have to increase the volume of the speaker. When invoking systemctl enable alsa-restore.service and systemctl enable alsa-store.service I do get the following error messsage: The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...). ... and it starts from the beginning after the next reboot. BTW it doesn't help when I change the settings in /etc/asound.conf from pulseaudio to the hw device. Thanks for any help Frank

[arch-general] RFC: Mesa and shared LLVM libraries
by Armin K. 03 Mar '13

03 Mar '13

Hello everyone, First, I am aware that ArchLinux is against patching packages to implement some features, but this might be worth the effort. Tom Stellard of AMD has announced a R600 backend patch against LLVM 3.2 few days ago [1]. It's basically his repository (llvm-amdgpu-snapshot) diffed against upstream LLVM (llvm). By applying the patch to ArchLinux LLVM package, one could benefit from enabling Mesa to link against LLVM shared library. Doing so, space would be saved and so the memory at runtime, too (I guess since it will use shared mappings). I've done some work regarding that. I've managed to split libLLVM-3.2.so from llvm package and put it into libllvm package. The package is a bit big though - the shared library contains all (~100) static libraries linked into one single library. The result is like this: Targets (1): libllvm-3.2-5 Total Installed Size: 21.77 MiB Building MesaLib against shared libLLVM-3.2.so saves space drastically. For all MesaLib produced packages, the output is like this one: Targets (6): ati-dri-9.1-2 intel-dri-9.1-2 mesa-9.1-2 mesa-libgl-9.1-2 nouveau-dri-9.1-2 svga-dri-9.1-2 Total Installed Size: 82.13 MiB Net Upgrade Size: -282.07 MiB 260 MB saved ... Looks nice to me. R600 backend will be part of LLVM 3.3 anyways, and this can be used in the future without patching anything. I am attaching patches for llvm and mesa PKGBUILDs to incorporate these changes. Do as you may please. If someone is interested in forwarding this to -dev-public list it would be nice. Have a nice evening. (As a side note, somehow llvm tarball sha256sum was wrong when I downloaded it). [1] http://lists.freedesktop.org/archives/mesa-dev/2013-March/035561.html

[arch-general] Qt4 documentation?
by Huang KangJing 03 Mar '13

03 Mar '13

Hi, I'm here to ask whether the qt4 documentation package will still be provided officially after such an upgrade from qt4 to qt5. I noticed that after qt5 was supported officially, certain qt packages were replaced by qt5 packages and qt4 packages were introduced, but as qt-doc was replaced by qt5-doc and qt4-doc didn't come up, I wonder whether this one will be supported officially.. Thanks. -- Huang KangJing 2012 Undergraduate, School of Physics,Peking University

[arch-general] Order of udev and autodetect HOOKS
by Sergi Pons Freixes 02 Mar '13

Hi All, Is there any impact on the system depending on the order of udev and autedetect? I mean, is the same HOOKS="base autodetect udev ..." than HOOKS="base udev autodetect ..." ? Cheers, Sergi
