#
# managing our work at the cryptobox
#
# usual workflow:
# dfsbuild - create the image directory with dfsbuild
# config - apply cryptobox specific changes to the image directory
# harden - remove unnecessary packages and disable developer features
# iso - create the iso image
# isoz - create a compressed iso image
# burn - burns the image on a cd-rw
#
# final action:
# release - the same as "dfsbuild config harden isoz"
#
#
# problems of this script:
# - has to run as root
# - 'harden' is strangely integrated
#
# you may run this script with multiple arguments, e.g.:
# cb-build.sh dfsbuild config isoz
#
# the action "release" does what it says :)
# (all developer's features like sshd, writable templates and
# the test-suite are deactivated, some packages get removed)
#
