Some of them are legitimate, many are not. (Not sure why ‘virtlogd’
doesn’t show up here.)

Yes, agreed. I’m not entirely sure where to document it; do you have
ideas?
(The doc in this area probably needs a Spring cleanup…)

The assumption is that services have been stopped by the time
‘user-processes’ is stopped (because they’re supposed to depend on it).
Thus, when ‘user-processes’ is stopped, normally only user processes are
left.

Agreed, I’ll see how to do that on the shepherd side.
Thanks,
