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

 227 Usage: mk-basefile [OPTION] ... DISTRIBUTION
 228
 229    -s                   Show list of supported linux distributions
 230    -a                   Add xtattrs, acl and selinux properties to the tar file.
 231    -f ARCH              Build for foreign architecture ARCH.
 232    -d DIR               Use DIR for creating the temporary subtree structure.
 233    -z                   Use gzip for compressing the tar file.
 234    -J                   Use xz for compressing the tar file.
 235    -k                   Keep the temporary subtree structure, do not remove it.
 236    -x CMD               Run CMD in chroot. If CMD exists as a file, copy it and run it.
 237                         Debian based only
 238    -h                   Print help.
 239
 240  Usage example: mk-basefile -J STRETCH64
 241  This will create a STRETCH64.tar.xz basefile.
