I simply was not aware of the existence of least-authority-wrapper. It
does look nicer that passing a slew of options to guix shell
--container.


It sure would be nice if shepherd could be used to manage those daemons,
just to avoid having two concurrent systems doing the same kind of work,
but I'd still need a way to monitor the /run/listen directory, and start
and stop shepherd services on the fly. It is probably doable, but it
is a huge refactor.
