# managing our work at the cryptobox
|
|
#
|
|
# usual workflow:
|
|
# dfsbuild - create the image directory with dfsbuild and copy it to
|
|
# the working directory
|
|
# config - apply cryptobox specific changes to the working directory
|
|
# iso - create the iso image (out of the working 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 (can be undone by "revert")
|
|
# revert - reset the working directory to the image created by dfsbuild
|
|
#
|
|
# final action:
|
|
# release - the same as "dfsbuild config iso"
|
|
#
|
|
#
|
|
# problems of this script:
|
|
# - has to run as root, because dfsbuild, config, iso, chroot, devel,
|
|
# revert and release need root privileges
|
|
#
|
|
# 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)
