Ubuntu PXEboot and preseed (like kickstart on RedHat)
Kickstart (+ pxeboot) is an automatic boot-install system for RedHat.
In Ubuntu/Debian, we uses pxeboot/pxelinux and preseed to do the same things.
PXEboot could be modified to have a boot menu,which's something like grub or lilo multiboot menu,
by editting pxelinux.cfg. So that we can have many deiiferent boot image to be choosen to boot the clients (newly install machines).
With ubuntu/debian "preseed", we can set preseed kernel boot-up parameters to auto-install server boxes.
