So, I guess my next questions is:
How do create the 2.88M boot floppy image with the MFS stuff on it? I
guess it merges somehow inside the kernel? Am I right? If so, how do i
compile my mfs into the kernel, and what do I put in the MFS?
Also, what files do I need to put on the boot floppy and what
configuration files do I need to edit? If I cannot mount the cd as /, and
only the MFS can be /, then can I at lease mount it as /usr? I am
assuming I would edit /etc/rc.local on the mfs root.
What I am wanting is a bootable cd that will take the user into an
automatic restore script, that will ask them to put the last tape in the
drive, and do a fdisk, disklabel, and newfs the hard drive, then restore
from tape. Basicly, it's a foolproof method for disaster recovery is what
i am trying to get at.
Thanks.
Sincerely,
Rick Duvall
