I’ve got 2 nearly identical dell poweredge 2200 servers, both of which I’m getting up and going with gentoo.

One, I got up and going last week. The other, I started on today. After reading some forum posts, I decided to try tar‘ing up the existing one and moving it over to the new machine.

About an hour (and 750 MBs) later, I ran grub, installed on the boot sector and rebooted. Working, optimized, up to date install in record time.

On source:
tar --exclude='/proc/*' --exclude='/dev/*' -cvf /tmp/image.tar /
On target:
scp user@source:/tmp/image.tar /tmp/
cd /
tar -xvpf /tmp/image.tar

So nifty.
