Christoph, maybe this is actually better addressed on the slony1-2 side.I completely agree that it should /also/ be addressed there, but nevertheless, init-functions should be sourceable from login shells.
I see it as a helper library for init scripts, not so much a general purpose shell library that can be sourced from arbitrary contexts. It wasn't really written with that in mind. To this day, I wasn't actually aware that anyone was using /lib/lsb/init-functions outside of an init script context. I don't think anyone is actually testing that it works for that.
