No, we cannot.  This would cause the init script to be run on boot via
/etc/init/rc.conf, in addition to the upstart job being run, with undefined
behavior.

Before you can drop this debhelper delta, we need insserv enabled in Ubuntu,
which first requires repairing the delta of packages that have had their
init scripts dropped completely in Ubuntu (at this point, possibly mostly
just the initscripts package).

2.  The masking support is done via startpar + startpar-upstart-bridge,
which is only available once we're insserv enabled.

So the steps are:

 1) fix all per-package deltas in Ubuntu that removed initscripts from the
    package in favor of upstart jobs (i.e.: bring the packages in line with
    current Debian policy wrt upstart jobs)
 2) undo the insserv/sysvinit/startpar changes that have disabled insserv in
    Ubuntu
 3) test insserv extensively in Ubuntu to make sure we're getting the
    expected result
 4) drop the debhelper change

  I feel like there's probably an existing systemd-ish way of doing
  this.
