Comment 4 for bug 571444

Same here (using Ubuntu 10.04 server). One of my hard drives is formatted with JFS but I forgot to install jfsutils. Now when I try to boot it says:

fsck: fsck.jfs: not found
fsck: Error 2 while executing fsck.jfs for /dev/sdb1
linuxroot: clean, ...
mount: wrong fs type, bad option, bad superblock on /dev/sdb1
       missing codepage or helper program, ...

mountall: mount /mnt/backup [650] terminated with status 32
mountall: Filesystem could not be mounted: /mnt/backup

And there the boot process is stuck. No shell, no login prompt, just nothing. Happens with "normal" boot as well as "recovery mode".

After installing "jfsutils" by using a live cd the problem has disappeared.
