Subject: systemctl: allow set-property to be called with a glob pattern
X-Git-Tag: v250-rc1~903
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=23a0ffa59f9cb26c4b016c9fd1a3a70da2607f61;p=thirdparty%2Fsystemd.git

systemctl: allow set-property to be called with a glob pattern

We call "systemctl set-property … Markers=+needs-restart" and this should
also work for globs, e.g. "user@*.service" or "syncthing@*.service".
