util.startup: Don't create installer plugin path (as root) Since this runs before dropping root, the directory ends up being owned by root, resulting in luarocks failing to install anything, since by then it would be running as the prosody user. luarocks creates this directory if needed, so creating it during startup is not necessary. One potential issue is if the directory is somewhere where Prosody can't write, but then you will simply have to create it yourself with the appropriate permissions.
