What would be the syntax you would use to rsync the 2 machines? There
are a lot of switches and suggestion in Google. I assume I would issue
the rsync command from the Knoppix booted machine? So far the syntax I
have seen suggested would be "rsync -a -e ssh user at masterserver:/boot
/tmp/newroot/boot", is that even close? I think this will all work
assuming Knoppix recognizes my SCSI controller. I think the format from
scratch will fix my boot loader problems. I haven't booted the machine
with Knoppix yet but did burn a CD this morning to have ready.
Right now I am trying a different approach (and it feels sloppy), I
loaded a minimal install of WBEL, booted the machine up and logged in as
root, then issued "rsync -a -e ssh root at masterserver:/ /" and it is
chuggin away. But I have a feeling this will just turn up crap :-)
