For a very long time RHEL-based systems have used service, chkconfig, telinit
for managing the init subsystem. This change to systemd is a big
change in that sense. So we thought that pushing the systemd control
utility into the older distributions would ease the pain.

yes - good point, I'll add the LANG setting in the script. xinetd has
always been a kludge -- see the man-page on xinetd. There are 2 'types'
that chkconfig knows about: 'sysv' and 'xinetd'
$ /sbin/chkconfig --list --type=xinetd
$ /sbin/chkconfig --list --type=sysv
I modified the script to try to deal with xinetd, and maybe I should have
just left it out.
cheers, etc.
