Subject: Minor changes mostly as discussed on the lists a few days ago:

 + SUBDIR.cpio.gz prevents files from SUBDIR/ to be copied when
   priming the memory filesystems. This restores the old behaviour
   and makes the copy process a lot more efficient

 + look for templates also in the list of directories supplied by
   bootp/dhcp via the T134 option aka kern.bootp_cookie

 + keep track of directories temporarily mounted with "remount"
   or "diskless_remount" commands and unmount them once we are done
   with them (at the end of this script).
