#  * because of the immediate restart needs, do some ugly stuff at the end to deal with that
#  * concern: TOO complex; the immediate restarts should not be needed...

#  * simplifying by making no immediate restart requests.  Assuming
#    that changes to app config files will be picked up by nginx_site
