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.
