Additional info:
The problem goes away after replacing systemd with /usr/lib/systemd/systemd in /usr/share/bash-completion/completions/systemctl (see patch attached) and reloading bash-completion rules.

Comment 1 Zbigniew Jędrzejewski-Szmek 2014-07-18 16:16:54 UTC
Thank you for the patch. The fix is more complicated, because we support installation of systemd binary in different paths (e.g. on Debian). A proper fix is upstream in http://cgit.freedesktop.org/systemd/systemd/commit/?id=c0a67aef31bb97.
