The check_perms_grsecurity.py script, if copied in your installed ~mailman/bin/ directory and run from there will modify permissions of files so that Mailman with extra restrictions imposed by linux kernel security patches like securelinux/openwall in 2.2.x or grsecurity in 2.4.x The way it works is that it makes sure that the UID of any script that touches config.pck is `mailman'. What this means however is that scripts in ~mailman/bin will now only work if run as user mailman or root (the script then changes its UID and GID to mailman). To make grsecurity happy, we remove the group writeable bit on a directories that contain binaries. Enjoy Marc MERLIN / - 2001/12/10
