Hi Michael,

the features are basically systemd-journal-gatewayd and systemd-journal-remote.
The package also provides /lib/systemd/system/systemd-journal-gatewayd.socket and /lib/systemd/system/systemd-journal-remote.socket which are just not enabled by default.
While journal-gatewayd is meant to be run as a sevice, journal-remote can be used also from command-line, script or custom service.

I use journal-remote in a custom service like this for example:
ExecStart=/lib/systemd/systemd-journal-remote --output=/var/log/journal/remote/remote-mc.journal --getter='/usr/bin/python3 -u -B /usr/sbin/mc-log mc 5600'

To make it work out of the box we could add options to enable the one or the other socket.

I don't see a good way to better name this option or make it more feature-oriented.

Artur

Don't change an existing goup id.

Hmm, systemd-bus-proxy should be removed first. It's no longer used. I'll
make a patch for that.

I'd like to see a more feature oriented option here. Both the name and how
it is used. I've never used this myself but from what I can tell, this is
used to send or receive a journal in push or pull mode. I'd like to see
options, that work out of the box without extra rules to actually make it
work.
You don't need to implement all use-cases. Just start with your use-case.
We can add others as needed.

Michael
