i really love the simplicity systemd offers.. so i was initially looking
for a way to maintain it and to do more complex conditions anyway - but
this complex logic can be processed outside of systemd if systemd
provides a way to just import the result.

the conditional checks we currently need are for example: hostname
matches pattern, userid still valid, ip-address X configured on any
device, etc..
