Definite problem here, too, on my uptodate Sid system, with ext3. My
fstab has lines like this:
LABEL=software /media/software ext3
defaults,user,exec,noauto 0 0
[The target is a LV within a VG on top of a partition on an external
USB disk.]
When the last field is 2, the boot stops after fsck fails with error
code 8, until I hit <ctrl>-D. From /var/log/fsck/fsck/checkfs
fsck.ext3: Unable to resolve 'LABEL=software'
fsck died with exit status 8

Probably a good idea. I just changed the fs_passno field to 0, but a
bug is probably in order.

Well, it's not really a bug in fsck, but, as you noted earlier, in
initscripts. Perhaps you can just reassign the bug?

Exactly. But mounting automatically is not the problem. You can have
them mounted, without the fsck being performed.
