Hi Wookey and Sven, thanks for your answers! They helped to stop looking for a non-existing solution, but find a (nearly) clean one:
(ab)use libwine (M-A:same) for the wineserver wrapper script.

Instead of adding this new package "wineserver", I'm (ab)using libwine now (which is "M-A: same" and depended on by wine32 and wine64 which have the binary). The only drawback is that libwine now ships a wrapper script for binaries, which are in packages that libwine doesn't depend on. I don't expect this to be an issue in practice, but still added a clear error message for that case. > (I think - I admit I haven't fully groked the wine package layout) Yeah, we're special ;) I'd be happy to explain this in more depth, just tell me. Greets and thanks again jre
