From 147a1201a526b3eac5ee6b0add543d5061db9943 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Wed, 29 Oct 2014 22:25:33 -0400 Subject: [PATCH] bash-completion: rework startable/restartable units once more I tried to use 'systemctl --all list-units' to filter unit files, but this always filters out unit files which are not loaded. We want to complete systemctl start with those units too, so this approach is not going to work. New version is rather slow, but hopefully correct.
