removed the "revert" feature (too complicated and rarely used) moved some settings to etc-defaults.d/cbox-dev.conf to allow local changes

# 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 (out of the image directory)
|
|
# burn - tries to burn the the image on a cd-rw (maybe it works)
|
|
#
|
|
# development actions:
|
|
# chroot - run first tests in a chroot environment
|
|
# qemu - run the qemu emulation
|
|
# devel - enable developer features like sshd, writable templates and
|
|
# the test-suite
|
|
# upload - copy your local files to tmpfs on a running cryptobox
|
|
# diff - compare tmpfs-files on a running cryptobox with the original
|
|
# merge - apply the diff to the local copy
|
|
#
|
|
# final action:
|
|
# release - the same as "dfsbuild config harden iso"
|
|
#
|
|
#
|
|
# problems of this script:
|
|
# - has to run as root, because dfsbuild, config, iso, chroot, devel
|
|
# and release need root privileges
|
|
# - 'harden' is strangely integrated
|
|
#
|
|
# you may run this script with multiple arguments, e.g.:
|
|
# cb-build.sh dfsbuild config iso qemu
|
|
#
|
|
# 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)
