Changeset 737 in MondoRescue


Ignore:
Timestamp:
Aug 3, 2006, 8:49:44 PM (19 years ago)
Author:
Bruno Cornec
Message:

Big NFS+PXE migration: start-nfs is not created by mondoarchive, but on the fly by init during restore. This allows more flexibility to restore through NFS a backup created on disks e.g. and simplify code.
