The default umask for init is 0; it seems that while systemd does set a more restrictive umask when necessary, it doesn't bother doing so when setting up the private socket, so it ends up having 0777 permissions by default... Either way, +x has no meaning on sockets (only +w matters). Checking `find /run -type s -ls`, it seems services aren't very consistent whether to keep or remove it for their own sockets... -- Mantas Mikulėnas <graw...@gmail.com>
