Neat, thanks for the initiative.

I would add the option to specify a (set of) runlevel, so that one can
disable a service just for a subset of the runlevels. I'm myself using
sysv-rc-conf for these things and frequently I remove links only for the
default runlevel.
It should also be considered what the default should be if no subset of
the runlevels is specified. To me, both "all" and "only the default
runlevel" make sense. Though probably "all" is better, as the default
runlevel can be changed later on without that update-rc.d notice
anything about that.
Similarly, a counter action for this new "disable" action should be
provided. I frequently dig into postinsts to retrieve the info about in
which position I should put back a service I've disabled. (Sure this
won't be needed with dependency based boot system, but in the meantime
it still is.)
Cheers.
