On my system (16.04), there are the files /lib/systemd/system/network-manager.service and /etc/init.d/network-manager, for example.
I don't understand how (and why) this works. I always restart Network Manager by sudo service network-manager restart. Shouldn't this mess up systemd somehow? It still seems to work.
Why does service --status-all list all kinds of services? Shouldn't 16.04 use systemd instead of Upstart?
Someone please explain how this coexistence works.
