Adam,

Thanks for progressing this.

The one concern I have is implying consistency of the /run/systemd files between
implementations of logind. AFAIK those files are used by the sd-login API
implemented in libsystemd and libelogind. But there are differences in the files
themselves, for example elogind doesn't support slices.

I suggest we specify logind as providing D-Bus login1 and Freedesktop sd-login
APIs.
