Note: pbuilder --create does not work well with relative build path,
base.tgz creation fails.
This led to the build_dir path being absolute.
Perhaps we should make it more granular and only use absolute paths for
pbuilder options.
Excluded:
Quagga (ideally, we should merge the vyatta changes into upstream).
Kernel and openvmtools (better built separately).
Firmware (better switch to upstream perhaps).
Everything that we used to build just because squeeze had it very outdated.
The idea is that package lists in data/package-lists/common/
will be used by all build flavours, while special individual
build flavours may have their own additional package lists
defined by configure options.
Split the 'iso' target into 'prepare' and 'iso' so it's possible to
debug the preparation stage without having to start an actual ISO build.
Add build and clean stages. Also add 'purge' target that "factory resets"
the build environment.
Add some tsun-tsun feel to the build log.
