Systemwide checkpoint/restart... seems like suspend-to-disk to me...: suspend-to-disk, but on the end, do not powerdown, but copy swap/filesytems to spare disks, simulate suspend failure and continue. On restart, copy back anddo restart. Perhaps with some LVM magic this can be made acceptable? Pavel -- (about SSSCA) "I don't say this lightly.
