system crash during upgrade

cell · 2013-07-12 08:07:38

First off my system seems to now work fine . I'm curious to where I messed up tho so I'll try to briefly tell you about my update this morning.

It's been 2 month since I last updated I followed the news.

pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm -
Resulted in grub-common from what I could google that should not matter.

[2013-07-12 07:04] [PACMAN] Running 'pacman -Syu --ignore filesystem,bash'
[2013-07-12 07:04] [PACMAN] synchronizing package lists
[2013-07-12 07:04] [PACMAN] starting full system upgrade

During the update X (I assume) crashed I still had sound but the system was frozen while flickering between a black and white screen. I had to cool boot.

On startup I got sent to busy box. I did a chroot into the system.

chroot /mnt/arch /usr/bin/bash
Cannot chroot '/bin/bash': No such file or directory

Not sure if it's related.

I rebuild the kernel then for some reason I decided to reinstalled grub too.

Now the system boots. As I started out I am wondering why this happened?

edit; was never able to find a useful clue and it has not repeated itself thanks for trying to help btw.

Are you wondering why X crashed or why X's crashing followed by reboot resulted in being dumped into the busybox shell?

I have no idea about the first.

Regarding the second, as I understand it, you rebooted before updating bash or filesystem, correct? So basically, anything looking for commands under /bin, /sbin or /usr/sbin would have drawn a blank because the upgrades you'd completed would have correctly moved everything to /usr/bin leaving those directories empty (except for bash etc.). The final upgrade of filesystem removes those empty directories and replaces them with symbolic links to /usr/bin which ensures that anything looking for stuff in /bin etc. will continue to find it. If you look in /etc/shells, for example, you will see that most shells are still specified as /bin/<shell> just for instance.

I'm not sure why X crashing prevented you from completing the upgrade. Did you try switching to another tty and just continuing at the command line? (Or restartintg X?)
