[Bug 672177] Re: libc6 upgrade causes umount to fail on shutdown because init cannot be restarted

[ingo]

Observed just another oddity, probably a separate bug in mountall?

I tried to mount the / filesystem (ext3) in journal mode to see if this improves the situation by adding the option to /etc/fstab:
data=journal,erros=remount-ro
But that results in boot process stalling with / filesystem mounted ro and just a console. dmesg | grep -i ext3 tells me:

EXT3-fs: mounted filesystem with ordered data mode
EXT3-fs (device sda1): Cannot change data mode on remount. The filesystem is mounted in data=ordered mode and you try to remount it in data=journal mode.

The only way out and to continue boot-up is to manually remount the fs rw by:
mount -o remount,rw /dev/sda1 /
and remove the data=journal option from fstab.
