Yes. As John says, you can use systemimager.


You can boot the nodes via a PXE boot and use a RAMdisk (ie. no
dependence on the hard drive). Format your hard drive, then sync them up
with an image from the install server using rsync (or another tool of
your choice). You can arrange for links in the pxe directory which point
towards different install methods, and remove that post-install so the
next time it boots it won't re-install! Or you can maintain state in
some other way, using flat text files or a small database.
The last step is either to reboot the machine, or you can do a
pivot-root such that the root partition on the hard drive now becomes
the filesystem root.
We run nodes with a normal hard drive install, a completely RAMdisk
based install or a mixed mode with /var and /tmp on local disk.

If you're writing your own system, Busybox might be useful
