Subject: systemctl: return an error code is status fails
X-Git-Tag: v213~199
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=5bb75bc745557d5141066dee796b329507b0c634

systemctl: return an error code is status fails

This got lost in the refactoring in f74294c1dabb4.

Also make sure that the return code corresponds to the *first* failure,
not the last.
