IOW unless the script isn't a mission to Mars script, chances are good
that somebody subscribed to this list could help you, if you would be
more precise about what you want to achieve, assuming you already
migrated to systemd. If not, don't even consider to write an upstart
script, migrate to systemd before writing the script, since sysvinit,
upstart and Co. are tem­pi pas­sa­ti.
