OK, now I'm home and can boot from the 5.4-RELEASE
disk 1 ISO and get to a fixit prompt. I can mount
/dev/da0 on /mnt and see all my data. Does anyone
have any idea what the right command might be to
restore my / drive so it can be mounted?
I'm leaving on a vacation tomorrow and would really
like to get this system up so I can post pictures and
such to my web page while I'm gone. I'd appreciate
any assistance as I really don't want to have to
rebuild the system tonight. I'm sure there's some
simple command that will restore access.
