# 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)
|
