I see two possible problem here (both solvable).

1. AFAICT shepherd currently does not depend on elogind at all.  Having
it as a run-time dependency might be fine on Guix (assuming we move
elogind into %base-services), but could be annoying on foreign
distributions, especially from non-root user's point of view.

2. How will the hook know what all processes it should let know?  There
is no global registry of all running shepherd processes no?

Though I am sure both of these are solvable.

Have a nice day (and thanks for the fix :) ),
Tomas
