The "pmbootstrap repo_missing" action is used exclusively by bpo. It
calls it only with these arguments:
pmbootstrap repo_missing --built --arch "$ARCH"
A blocker for merging systemd into pmaports master is, that the
current repo_missing code cannot display packages that are both in
extra-repos/systemd and in another path. I have considered just not
supporting this and discussed doing that with Caleb and Clayton, but we
figured it would be a major obstacle in the future to not be able to
easily override packages with systemd specific versions (currently we
need this for 3 packages).
Integrating this into the existing repo_missing code would be hacks upon
hacks. Also the scope of the current repo_missing code has many extra
features that are not used and would be extra effort to carry along:
* Allow specifying a pkgname
* Running without --built
* --overview
So I decided to replace the repo_missing code with a much simpler, more
modern implementation, that does exactly what is needed:
* Duplicate packages in systemd and non-systemd dirs are displayed
* The output always include all packages, no matter if they are already
built or not (same behavior as with --built)
* Removed --overview and selecting specific packages too
* The code for filling "repo" (either "systemd" or None) is more
resilient now, as it can use proper relative paths to the root of
pmaports. Unlike the previous implementation, it will not fail if
subdirs are added to the systemd dir.
I have made sure that the output is exactly the same as before on
current pmaports master.
