Machine Replication

[Karl Denninger]

I had a shell script that would replicate a machine when I ran my ISP; you
put the loader and partition table, plus a minimal system on the new machine,
then ran the script and pointed it at the "source".

SSSSLLLLUUURRRRPPP!  In about 20 minutes it was done.

Not hard to do at all with a simple shell script.....

Used this all the time to "push" new OS versions out to the cluster (a
couple of dozen machines) when I was done testing them.... as well as
adding new machines to the existing cluster as demand warranted.
