Subject: [PATCH] sysvinit: Fix is_selinux_enabled() for libselinux
is_selinux_enabled()!=1 means SELinux is disabled by kernel
or SELinux is enabled but policy is not loaded.
Only at this time, /sbin/init program should call
selinux_init_load_policy() to detect whether SELinux is enabled
and to load SELinux policy.
This is fixed already in the upstream sysvinit,
http://svn.savannah.nongnu.org/viewvc/sysvinit/trunk/src/init.c?root=sysvinit&r1=72&r2=90
