Subject: [PATCH] - create/remove unit files in normal generator directory -
 prefix service and socket units with "rc-inetd-" - ensure that exit status of
 the per-connection processes is forgotten, to   make sure that systemd won't
 keep around information for numerous possibly   failed connections - nowait
 means "Accept=true" (http://0pointer.de/blog/projects/inetd.html) - properly
 set stdin and stderr
