I'm seeing the following denial while installing RPMs. =20

type=3DAVC msg=3Daudit(1560944462.698:217): avc:  denied  { map } for pid=

curity_t:s0 tclass=3Dfile permissive=3D1

The RedHat targeted policy has the change in this patch.  I'm not sure if t=
his is preferred, or
if it would be better to create a new interface 'selinux_map_security_files=
' (or similar).
