[systemd-devel] "systemctl --all" does not really list all units

[Foudil BRETEL]

Hi all,

I know this is the devel list, and that there are maybe more important things, but from my user perspective, this is really annoying: https://bugzilla.redhat.com/show_bug.cgi?id=748512

Are we only handful to find that 'systemctl list-unit-files' is just misleading, since users are dealing with units, not unit types ?

Here is the my comment:
> Another problem is when you want to list inactive units, for example to find out which ones you can start (that's what the bash completion script for systemctl tries to do). You then need 2 commands:

>   systemctl list-units --all | grep ' inactive '
>   systemctl list-unit-files | grep ' disabled'

> As a user, I do not want to deal with implementation aspects, I want to deal with units (all of them).

BTW, systemd-bash-completion.sh is wrong at finding startable units.
