# nodumprpm - Mark all nonconfig files in an rpm with ext2 "nodump"
#   flag, since they're recoverable from the rpm file.
#
#
# Usage:
#   nodumprpm MODULE
#     - Mark all nonconfig files in MODULE (an installed module).
#   nodumprpm -p FILE
#     - Mark all nonconfig files in FILE (a .rpm file).
#   nodumprpm -a
#     - Mark all nonconfig files in all installed modules.
#
# Note:
#   If a full restore is needed, you need some way to determine which
#   packages need reloading.
