1.
The 'nix restore process is working. My process is as discussed
earlier, install a base system with bacula and restore everything except
- /sys /proc *and* /boot. I learned quite a bit about getting the drive
configuration right, but I successfully restored a working RH server.
2.
I'm still interested in testing the new recovery cd solution when Kern
returns.
3.
Now, I'm trying to conquer OSX 10.4... I saw a couple of posts here,
but it doesn't look like anyone's *actually* done it by restoring the
system. I don't mind figuring it out, but if you can give me a push in
the right direction or keep me from repeating your mistakes I'd
appreciate the time saved.
Almost everything I've read says to use imaging or reinstall everything
and restore only the data. The bootcd solutions I found are not for
<10.4 or based on creating a bootcd from the OS installation disk. There
are a couple of commercial products, but my goal is a one-stop solution
that a backup expert can use without being an OSX expert, too. That
said...
Should I try doing it the same as for 'nix, but using the above-
mentioned bootcd? Is BSD significantly different (all my 'nix are RH or
CentOS), and if it is should I start with that process? I do actually
work on these systems, but mostly remote and on the command line.
TIA for any/everything.

Thanks for the education. I knew about /proc, but /sys is news to
me.
Again, many thanks.
