"systemd --user" service? Trying to do so will fail with:

I think it's crucial to clear that point to avoid confusion in this discussion
where people are talking about different things.

On the other hand running "systemd --system" service with:

User=nobody
AmbientCapabilities=CAP_NET_ADMIN

is perfectly legit and clears some security concerns as only privileged user
can start such service.

While we are at it, can we please stop looking at this from a systemd only
perspective. There is a world outside of systemd.

Thanks,
