Re: Why is there no tool to make an identical installation on several PCs - or is there



To those who pointed out that my question had already been answered,
thanks for pointing it out.  I feel quite silly enough now, and will
actually follow links in interesting discussions in future ;-)

This is not really a satisfactory solution for my situation.  I have a
server running services that I want as close to 24x7 as possible
without buying duplicate hardware to do active failover.  Our disaster
recovery plan for this machine currently consists of:

 * Stick a redhat 7.2 CD in the CD drive.
 * Reboot machine.
 * At LILO boot: prompt, type 'linux ks=http://x.x.x.x/machine.name/ks.cfg'
   and hit enter.
 * When it finishes doing its stuff, it will reboot.  Take the CD out
   then.
 * Login as root and change the passwords for a list of accounts.

And that's it.  It is fast and easy; most software problems we don't
bother trying to fix, we just rebuild the machine from scratch.  If
the problem would have taken 20 minutes to fix then we are still in
front.  Taking a HD out and hooking it up to another machine is messy
because it means taking the cover off, you need the other machine
physically present, and you always run the risk of dropping something
or sticking a screwdriver in something you shouldn't have, especially
when your server is down and users are howling for blood.
