Subject: bus-proxy: allow empty arguments to UpdateActivationEnvironment()
X-Git-Tag: v224^0
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b2a0ac5e5b29c73ca7c0da23369a4769d5a91ddd;p=thirdparty%2Fsystemd.git

bus-proxy: allow empty arguments to UpdateActivationEnvironment()

There is no reason to prevent empty argument lists on
UpdateActivationEnvironment(). Make sure we don't fail, but still skip
the call to pid1.
