   3 # mk-basefile, create basefiles for some distributions
   4 #
   5 # Thomas Lange, Uni Koeln, 2011-2017
   6 # based on the Makefile implementation of Michael Goetze
   7 #
   8 # Usage example: mk-basefile -J STRETCH64
   9 # This will create a STRETCH64.tar.xz basefile.
  10
  11 # Supported distributions (each i386/amd64):
  12 # Debian GNU/Linux
  13 # Ubuntu 14.04/16.04
  14 # CentOS 5/6/7
  15 # Scientific Linux Cern 5/6
  16 #
  17 # Packages you might want to install to use this command:
  18 # debootstrap, rinse, xz-utils
  19
  20
  21 # Define your local mirros here
  22 # For the first stage, set the CentOS/SLC mirror in /etc/rinse/rinse.conf

 218    Copyright (C) 2011-2017 by Thomas Lange
 219
 220 Usage: mk-basefile [OPTION] ... DISTRIBUTION
 221
 222    -s                   Show list of supported linux distributions
 223    -a                   Add xtattrs, acl and selinux properties to the tar file.
 224    -f ARCH              Build for foreign architecture ARCH.
 225    -d DIR               Use DIR for creating the temporary subtree structure.
 226    -z                   Use gzip for compressing the tar file.
 227    -J                   Use xz for compressing the tar file.
 228    -k                   Keep the temporary subtree structure, do not remove it.
 229    -h                   Print help.
 230
 231  Usage example: mk-basefile -J STRETCH64
 232  This will create a STRETCH64.tar.xz basefile.
