Description Mike Hearn 2004-05-08 19:29:20 UTC

Apologies if this is the wrong component, I was not sure where to file
it. If the line for the root filesystem is missing in /etc/fstab then
bootup will fail apparently due to fsck being passed "/" as an
argument rather than a device. This prints an uber-scary message about
the superblock being toasted and drops you into a recovery console.

I have no clue how my machine got into the state where it was missing
this entry. I did an an unclean shutdown but it's a rather odd
"corruption" to get :)

If you look at /proc/mounts, you'll have:

[notting@nostromo: ~]$ cat /proc/mounts
...
/dev/root / ext3 rw,noatime 0 0
...

Hence, it's a bit more code to dig out the root device name.

Probably won't fix this at this point.
