For the latter, we don't have a snappy interface to restart services (we
could expose one, not sure about the granularity though), for now here's a
cheatsheet:

Manage and check state:
sudo systemctl [start|stop|restart|status]
[package_name]_[service_name]_[package_version].service

eg; webdm 0.6 has a service called avahi, so I would

sudo systemctl start webdm_avahi_0.6.service

Check logs
sudo journalctl -u [package_name]_[service_name]_[package_version].service

e.g.; to check the aforementioned service's logs:

sudo journalctl -u  webdm_avahi_0.6.service
