Subject: systemctl-completion: always invoke with --no-legend
X-Git-Tag: v38~223
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74eeab044e506a39786f484b160d9f64d48ad243;p=systemd

systemctl-completion: always invoke with --no-legend

In the case of completion for the 'restart' verb, passing the invalid
unit name (the colums header) causes completion to cease functioning
entirely, with the error:

  Failed to issue method call: Unit name UNIT is not valid.

This adds a small wrapper function for systemctl which can have common
options added to it.
