Using the "declare -x" build-in instead of "export" allows variables
to be exported only to child processes that are executed in the scope
of the function in which the variables are declared, including nested
function calls.
This avoid polluting the environment of every package build that
follows.
By using --cores argument to rootfs.py, JOBS= is set in the
live-bootstrap environment, and -j${JOBS} is used on builds. This speeds
larger packages up significantly.
A fair number of packages do not build properly with parallelism. Most
of these, at least for now, are disabled with -j1.
- Rather than defining the urls where they are gotten (python sysa,
python sysc, inside sysc), a spec file is now used that is easily
interpretable and tool-independent.
- This is interpreted by rootfs.py and inside sysc.
- This is also used to make sources available and extract sources.
- Manual dirname selection is no longer required as is tarball renaming
upon download - all of this is handled automatically.
