tlug: Re: fsck error on boot

[regan.nayve@example.com]

greetings,

thanks for the suggestion.
i tried your suggestion and also mount -n -o remount,rw / but
also failed with an error saying "mount:can't find / in
/etc/mtab or /etc/fstab"....this might probably cause by
the corrupted fstab.

i guess the best way to change the corrupted fstab is thru
a boot disk.i then tried to make a boot+root disk following
the 'bootdisk-how-to' but during transfering the root filesystem
(dd if=rootfs.gz of=......) the system signaled an error that
there is no file such as rootfs.gz.

has anyone of you experience this error while making boot+root
disk?

thanks,
Regan Nayve
