running maintainer scripts. This is a work-in-progress. If you build_image like: EXPERIMENTAL_NO_DEBOOTSTRAP=1 ./build_image.sh it will skip debootstrap and install the base required packages without running maintainer scripts. This is about 68 packages that have lots of interleaved dependencies so it is nasty to trim down. If you build like: EXPERIMENTAL_NO_MAINTAINER_SCRIPTS=1 ./build_image.sh it will install all packages skipping maintainer scripts. Using these we can try and get things in a state where we can create an image built of cross-compiled packages. This is obviously not finished but in this case I prefer to commit early so others can poke at it. Review URL: http://codereview.chromium.org/527015

# This script can be used to replace the "dpkg" binary as far as the
|
|
# "apt-get install" command is concerned. When "apt-get install foo"
|
|
# runs it will make two calls to dpkg like:
|
|
# dpkg --status-fd ## --unpack --auto-deconfigure /path/to/foo.deb
|
|
# dpkg --status-fd ## --configure foo
|
|
# This script will extract the .deb file and make it appear to be installed
|
|
# successfully. It will skip the maintainer scripts and configure steps.
|
|
#
|
|
# As a one-off test, you can run like:
|
|
# apt-get -o="Dir::Bin::dpkg=/path/to/this" install foo
|
|
|
|
# Load common constants. This should be the first executable line.
|
|
# The path to common.sh should be relative to your script's location.
