Subject: Prep v231.3: No authorization for setting the wall message.
X-Git-Tag: v231.3~6
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=b2b26ba0d92656fa06767a58d30701d1f57a7e58;hp=e194a8049eaf9a86c16d1d3d31a3331255b39bc7;p=elogind.git

Prep v231.3: No authorization for setting the wall message.

elogind only calls this when shutting down, rebooting or cancelling a
pending shutdown/reboot. Authorization is already needed there, so do
not question the user twice, just because they forgot to sudo.
