There could be other entities somewhere that aren't units and aren't mentioned in the man page. Or perhaps they are but aren't called that. However, according to [1], "entity" is a synonym for "unit". So what exactly does the quoted sentence from the man page try to explain?

So what does it actually do? And I can only guess that it's called "systemd" because it provides a "system" and is a daemon. But is it a daemon? Looking at [2], it is not because it's controlled by a user (through systemctl and journalsomething and perhaps other things I don't know about). Actually, it's more like an MCP, if you've seen Tron.

What do you expect when "disabled" means something like "not so much enabled" and "mask" means "disabled"? I made a bug report about that, and they decline to even fix a simple thing like that. -- Fedora release 20 (Heisenbug) -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
