Run fsck from the boot prompt

[Mark Haney]

is there a way to run a fsck from the boot prompt?  I have a machine here  
that is pretty well FUBAR, I can't even get it to a CLI to run fsck.  Any  
ideas?

Mark,

Have you tried bringing it up in single user mode? Grab GRUB's attention
at boot time and append a " 1" or " single" to the "kernel
/vmlinuz-2.4..." line, then let the boot continue. If this doesn't work,
try again with " emergency". If THAT doesn't work, try CD #1 or the Rescue
CD.

Good luck...

Can the kernel mount the root filesystem?

Try booting with init=/bin/bash and then run /sbin/e2fsck manually.

Hey that did it.  Thanks for that, I knew about booting 'single', but  
never the init=/bin/bash command.  That's a lifesaver.  Thanks.
