Subject: polkit: if PK is not around, consider this a permission denied error
X-Git-Tag: v196~64
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=8885064fd00d74feb16334d645f9c479735090c3

polkit: if PK is not around, consider this a permission denied error

Uninstalling PK should cleanly disable PK authorization but not result
in further runtime errors.
