Subject: Redirect stderr when calling shutdown, too
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=trigger-rcmd.git;a=commitdiff_plain;h=8ef4954fc0372206f7d6ee8a3efbe07cb7de708f

Redirect stderr when calling shutdown, too

This is required to not trigger "error detection" of some mail wrapper
scripts etc., that would notice output og shutdown(8) on stderr -- which
outputs messages there, even when there is NO error ...
