Changeset 3057 in MondoRescue for branches/3.0/mondo/src/restore-scripts/mondo/make-me-bootable

Message:

• Fix #611 by changing make-me-bootable to first desactivate all active partitions on the given disk, and then reactivate only the one needed (change of interface for this script). This remains not very satisfactory, and storing active flags at backup time would probably be better, but would require to handle HW modification cases with this script anyway.
