# nodumptgz: Mark all files in a tgz archive with ext2 "nodump"
#   flag, since they're recoverable from the tgz file.  Be sure to remove
#   the -d- flag from config files that you modify!
#
#
# Usage:
#   nodumprtgz FILE.tgz
# Be sure your current directory is set correctly for relative paths in the tgz!
#
# Note:
#   If a full restore is needed, you need some way to determine which
#   packages need reloading.

# We must remove directories, since +d for a directory is inherited by files
# created in the future
