*shrug* We don't have anything like that, so it's not realy relevant.

Well, yes, but we shouldn't have random errors occuring all the time in
normal use.

ie, not having any "fallback" options, just always translating invoke-rc.d
foo blah to /etc/init.d/foo blah or a no-op, depending on runlevel.

That way running a postinst works cleanly whatever runlevel you're in,
and whether you've implemented "maybe-restart" yet or not, and so on.
