Upstream openssh-portable has a proposed patch which simply
implements the sdnotify protocol directly. That would
provide the benefits with none of the over-linking risk.
https://bugzilla.mindrot.org/show_bug.cgi?id=2641#c13
It could use some review from distro folks familiar with
sshd systemd integration.
(The wider point about splitting the sdnotify functionality
is still quite useful, to avoid everyone re-implementing the
same thing and possibly adding bugs in _that_ process.)
