-Subject: [PATCH] Add root/admin user detection
-
-This patch detects whether or not the server is currently executing as a privileged user and spits out a warning.
-The warning serves as a sort-of PSA for newer server admins who don't understand the risks of running as root.
-We've seen plenty of bad/malicious plugins hit markets, and there's been a few close-calls with exploits in the past.
-Hopefully this helps mitigate some potential damage to servers, even if it is just a warning.
