Could we not provide a libsystemd-daemon.so.0 that is just a stub and
links to libsystemd.so.X and just calls the functions therein? That way
the API could still be provided with the old lib (and old .pc files too)
until such times as everything is updated. I would presume the name
mangling would allow for this to work OK with some clever tricks here
and there... (correctly me if I'm wrong)

This would surely be the nicest way to handle things during any
transition phase and could be turned off with a configure switch?
