   5 # Thomas Lange, Uni Koeln, 2011-2017
   6 # based on the Makefile implementation of Michael Goetze
   7
   8 # Supported distributions (each i386/amd64):
   9 # Debian GNU/Linux
  10 # Ubuntu 14.04/16.04
  11 # CentOS 5/6/7
  12 # Scientific Linux Cern 5/6
  13 #
  14 # Packages you might want to install to use this command:
  15 # debootstrap, rinse, xz-utils
  16
  17
  18 # Define your local mirros here
  19 # For the first stage, set the CentOS/SLC mirror in /etc/rinse/rinse.conf

 203 mk-basefile, create minimal base files for a Linux distritubtion
 204
 205    Copyright (C) 2011-2016 by Thomas Lange
 206
 207 Usage: mk-basefile [OPTION] ... DISTRIBUTION
 208
 209    -s                   Show list of supported linux distributions
 210    -a                   Add xtattrs, acl and selinux properties to the tar file.
 211    -d DIR               Use DIR for creating the temporary subtree structure.
 212    -z                   Use gzip for compressing the tar file.
 213    -J                   Use xz for compressing the tar file.
 214    -k                   Keep the temporary subtree structure, do not remove it.
 215    -h                   Print help.
 216
 217  Usage example: mk-basefile -J STRETCH64
 218  This will create a STRETCH64.tar.xz basefile.
