First, if you are running 10,000 machines with 512K RAM, you are doing
something really, really weird or you just like managing a lot of
machines that can't do very much each - and supplying a lot more power
than you would need for fewer, more capable hosts.

But, if you have even more than a few, you are probably already doing
some sort of image installs.  So just install on a machine or VM with
1GB, then use ReaR or Clonezilla to back it up and restore onto the
target boxes.   Or for brute force, use dd to copy the drive and swap
them into place.
