Yes.  'ps -ef | grep xfs':
xfs       2776     1  0 Sep23 ?        00:00:00 xfs -droppriv -daemon

I find xfs is listening on a socket in /tmp/.font-unix

'netstat -lp | grep xfs' (output is wrapped):
unix  2      [ ACC ]     STREAM     LISTENING     6861
2776/xfs            /tmp/.font-unix/fs7100

'ls -la /tmp/.font-unix':
total 28
drwxrwxrwt   2 root root  4096 Sep 23 19:53 .
drwxrwxrwt  18 root root 12288 Sep 28 10:44 ..
srwxrwxrwx   1 xfs  xfs      0 Sep 23 19:53 fs7100

   daemon xfs -droppriv -daemon
   ret=$?
   [ $ret -eq 0 ] && touch /var/lock/subsys/xfs

}

As you can see, xfs apparently uses $FONT_UNIX_DIR as the path for
creating a socket to listen on, and this directory and its contents are
wiped out and recreated every time before xfs is started.
