Re: backups & booting emergency partition




  I believe that the booting by uninformed staff can be done, if you have
a prepared emergeny boot floppy that has a script to re-run lilo on
another disk (which must contain the obvious essential things). This would
be normally mounted as a disk on the 'primary' disk while it is working. 

  This way, if it crashes, the staff would have to:

1. Change the LUN of the 2nd disk to the 1st one's or such (or even NOT).
For IDE disks they MUST switch the jumpers etc. Sorry.
2. Insert the emergeny floppy and reboot from it.
3. Remove said floppy when prompted (to let the system reboot, this time
from the 2nd disk).

  The most complicated button to be handled by staff in this case, is the
power switch. They also have to read the screen, to know when to remove
the floppy.

  The complications occur when doing updates on setup scripts as they have
to be mirrored to the second, and the second disk can hardly be one of the
'usually' mounted partitions ( i.e. /usr etc).
