- Add a new %upstream macro to support building from upstream sources. This
will allow upstream to build systemd rpms using the opensuse systemd packaging
specs. These rpms will be built and used in upstream's mkosi based hacking and
testing environment to test changes and in the future to run integration tests
as well. By building the rpms using the opensuse packaging specs, the idea is
to catch more issues ahead of time as the mkosi environment will behave more
like a regular opensuse system.
- Add new %version_override and %version_release macros to allow overriding the
version and release of the rpm respectively.
