Yes but that is the identity field in the security context tuple. It is
not the type field. The identity field is used to map ( amongst
categories/sensitivities ) roles to linux logins. The type field is used
to enforce integrity.

In any case, You can ignore this issue, or you can use the run_init
command when you manually (re) start a service (run_init service httpd)

In fedora no policy is enforced based upon the first field of the
security context tuple. It is only used for mappings.
