Re: How to fsck read-only-mounted root filesystem?

["Jesse W. Asher" <jasher1@xxxxxxxxxxxxxxx>]

You have to remount it on the fly.  Look at the man page for "mount" and 
look at the remount option.  You should be able to do something like 
"mount -o remount,rw /"  or some such.  I'm not sure this is the exact 
syntax, but you should be able to figure it out.....
