Looking for ideas how to get this working. I think I need a way to run %preun scripts as unconfined, but I'm not sure. I haven't had much luck trying to find useful selinux documentation.So why don't you just use "systemctl stop"? That seems to be a lot simpler and more correct.
The main rpm package starts all services. All application services run under the same systemd service, and the startup script takes an inventory of which subpackages are installed, and starts each one's daemon. That seems even more simpler: a single systemd service, instead of half a dozen of them.
Except that if one subpackage gets removed, it needs to stop just its own service. This is easily done, except for selinux.
Now, I could also have subpackage rpms' %preun run systemctl stop, and %postun systemctl start, restarting everything, except for the removed services. But that's terrible.
