File context pattern is missing in RHEL-6.7: # matchpathcon /var/run/chronyd.sock /var/run/chronyd.sock system_u:object_r:var_run_t:s0 # File context pattern is defined on RHEL-7.2: # matchpathcon /var/run/chronyd.sock /var/run/chronyd.sock system_u:object_r:chronyd_var_run_t:s0 # Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
