[Bug 468450] Re: Mount of root filesystem failed

[Jason Ansaldo]

I ran into this issue Yesterday, but was able to solve it.

I had let my Ubuntu system run over the weekend.  When I got back to
work Monday there were some odd behaviours.  Wine no longer had access
to my network device, and I lost Sudo access (as noted above).  I
rebooted and got the errors listed right after the Ubuntu startup screen
(just after GRUB).  None of the listed Kernels worked.

After trying everything listed here I found a second error pointing to a
Bogus Option when mounting devpts.

This finally got me to the root of the problem.  My /etc/group file had
been purged of all but a couple of entries.  This was causing all of the
errors.  Using the liveCD I was able to browse to the following link and
get a default /etc/group file

http://psychocats.net/ubuntu/sudo

I also had to add an entry for gdm to get X to start on my build

gdm:x:113:

This got me back up and running again.
