So if you hand-hack these PAM files to refer to pam_elogind then
do things work without the symlink? This would at least tell us if
this is all we need to fix in these other packages, or if there are
other places that are using pam_systemd.so directly somehow.

lightdm-greeter seems like a straightforward one (though we probably
need to sort out how to let lightdm say "use whichever of systemd
and elogind is present" somehow -- listing both will work provided
they aren't both installed and you don't mind warnings about
missing files in your auth.log).  I never got round to figuring
out what the runuser-l pam file was for -- does anybody know?
