Boot failure

So I've been thinking about how to run fsck...

At the moment, I have to boot from an install cd, go into fixit mode,
and mount filesystems by hand. I am mounting them to a mount point
like /mnt/root and /mnt/home, etc.

Do I just do a command like:

fsck /mnt/root

Should I use any flags? Should I mount the filesystems read write or read only?
