Comment 109 for bug 1197395

Well, there is never geing to be a "fully functional" implementation of "su -" because it always inherits state from the session, and that state is quite substantial.

I mean, you can reopen this bug as much as you want, but I fundamentally believe that the scheme of "su" (or "su -" if you want to nitpick), can never work for desktop applications. You can lie to yourself, and claim D-Bus wouldn't exist and what else, but I don't see why systemd should play this game of pretending.

I am not binding our session definition to the audit sessionid because it was the same thing, but because it turned out to have the same lifecycle, and we thus just decided that we can avoid a new identification scheme, and just reuse the id audit introduced.

Anyway, closing again. This can never fly. And the same way as the destination user might or might not get access to the bus, it should also get or not get access to the XDG_RUNTIME_DIR. It's the same thing. And to PA, and whatnot. I am not going to handle XDG_RUNTIME_DIR differently from the rest.
