Description Michal Jaegermann 2012-02-09 21:03:55 UTC 
Description of problem:

After an update to dracut-015-1.fc17 and kernel-3.3.0-0.rc2.git6.1.fc17 all attempts to boot end up with "cannot find init" from dracut and in a dracut "debug shell".  'init' is there sitting as an executable /bin/sh script in the top directory if initrams.  Attempts to restart a machine from there fizzle with "Failed to talk to init daemon" errors.  If you will try in this debug shell run explicitely './init' then it starts going through motions and runs fsck on /sysroot/usr but eventually chokes with:

mount: can't find /sysroot/usr in /etc/fstab.

Actually /etc/fstab has only two identical lines, like this, in it:

LABEL=/usr1 /sysroot/usr ext3 defaults 1 2

and 'mount LABEL=/usr1 /sysroot/usr' or 'mount -L /usr1 /sysroot/usr' work just fine although 'mount /sysroot/usr' fails with "can't find".

The only things I was able to do in this moment was either power switch or a kernel panic after 'exit'.

Version-Release number of selected component (if applicable):
dracut-015-1.fc17

How reproducible:
always

Additional info:
Is this another instance of binutils bug 788107? An attempt to boot the same kernel with a dracut-014-77.git20120126.fc17.1 generated initramfs got stuck with a claim that 'init' is not executable and I did not get even a debug shell (which does not seem to be that useful anyway).

Still broken in rawhide with dracut-015-7.fc18

Proposed patch

can you try the attached patch on /usr/lib/dracut/modules.d/98usrmount/mount-usr.sh ?

With initramfs generated by dracut-015-8.git20120210 + this patch my machine booted 3.3.0-0.rc2.git6.1.fc17.x86_64.  Thanks!
Comment 4 David Ward 2012-02-11 05:00:14 UTC 
Works for me too, please commit fix.
Comment 5 kevin martin 2012-02-11 14:54:50 UTC 
neither applying the patch nor rebuilding the initramfs has fixed the issue with me.  I opened a new bugzilla for this ( 789503 ) and will post updates there if I see anything more.

seems to have fixed it.  Thanks.
