If the servers are all identical hardware, I would just build one machine, then
boot each other box off a live CD, and dd the contents of the entire
drive/array over. (You could do this partition by partition as well.. but if
you do the whole drive/array you only have to do it once.)
dd if=/dev/<DRIVE/ARRAY> | ssh [EMAIL PROTECTED] "dd of=/dev<DRIVE/ARRAY>"
That should do it. (as long as the hardware is identical.) Of course.. it will take time to
transfer, and you'll have to change the IP's & hostname of each server. This is a lot like
making & deploying a GHOST image.. it's just skipping the "make" part and moving
right to deploy. You could also send it to a file, then DD the file into place on each host from
a DVD if they're small enough (or bzip2 compress them to see if they can be made to fit.)
If you're doing machines that aren't identical, but you can use a standard
structure for most disk elements (same size /boot, /, /var, /usr, etc..) you
can build one machine, create an image for each of the standard partitions, and
dd those over.
You could create a tarball that has the kernel, including /boot, /usr/src,
/lib/modules etc.., but you might not end up with world files that are in-step
with what's actually on the machine.
I hope this is helpful.

Hi guys,
in the near future i am looking at installing gentoo onto a number of
hosts. i already have a buildhost preparing binary packages for the
clients - one of the missing pieces is the kernel install.
i'd like to avoid having to compile a kernel on each and every host. how
do you install a prebuilt kernel onto the host, fx. after having deployed
a stage4 using quickstart? the best thing i can come up with is writing
my own custom script, which pulls a tarball via http. the tarball has the
modules, the initrd and the kernel...
thanks.
kind regards
Thilo
