Denial relabeling /run/systemd/private
I am seeing the following denial (in dmesg) during system startup:
[ 4.623332] type=1400 audit(1507767947.042:3): avc: denied { relabelto } for pid=1 comm="systemd" name="private" dev="tmpfs" ino=5865 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=sock_file
It appears that systemd is attempting to relablel the socket file /run/systemd/private to init_var_run_t but doesn't have permission.
Updated to create new interface for relabeling of sock_files rather than adding to existing interface
