Subject: [PATCH 2/2] =?UTF-8?q?Bug=2023867=20=E2=80=93=20UnixProcess=20vs.=20SystemBusName=20aliasing?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For now, convert SystemBusName to UnixProcess when storing/checking
temporary authorizations. See
http://git.gnome.org/cgit/PolicyKit-gnome/commit/?id=ad5fe38a1f7a7a670c3d8e9384b9cd0d037c9222
for a test-case for this.
