Actually I just tried Clonezilla for the first time last week, the server edition, on the drbl live distro and everything I've thrown at it is cloned and restored, that is 3 different systems, one being a Mac. This Clonezilla SE edition is able to let clients (store and restore) boot with PXE, i.e. no boot cd or usb. Restoring with the drbl live is set up to max. 40 simultaneous restores (we will use pxe again here) in a multicast setup,
Clonezilla differs from partimage by storing all necessary information (mbr, partition info and the partitions) in a folder,
I'm having some issues compiling parts of the clonezilla utils in PClinux at the moment but eventually I plan to build the entire drbl+clonezilla complex to be included in Synaptic,
cheers,
