From 160481f68d0a5f26f75c04fb576fb854fd5416a5 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Thu, 15 Mar 2012 19:06:10 +0100 Subject: [PATCH] systemd: mount the securityfs filesystem at early stage This is an S/MIME signed message The mount of the securityfs filesystem is now performed in the main systemd executable as it is used by IMA to provide the interface for loading custom policies. The unit file 'units/sys-kernel-security.mount' has been removed because it is not longer necessary.
