[Pkg-shadow-devel] Bug#814670: login: su - clears XDG_RUNTIME_DIR

[Vivek Das Mohapatra]

The problem is that libpam_systemd.so (which normally sets up the XDG_* 
variables, I think) is detecting a pre-existing audit session and bailing
out.

Background:

I'm looking into a possible fix to make su - and similar work properly again
in this scenario, if you'd be interested in testing it (although obviously
don't just take my word for it and install random libpam components from 
strangers on the internet - I'd advise you to use a throwaway VM).

I don't have an ETA yet, just started digging into the problem,
but I thouhgt I'd post and let you know it was being looked at.
