Maybe, but I wouldn't rely on it...  The OSX installer has some very
severe limitations, and sorting them out is pretty difficult.  Right
now, it treats all major distributions as increasing versions of the
same product, which is why you had to do deal with receipts.

I think that they kept referring to future versions of the Installer
thing that will solve some problems, the feeling I had about it is
that tey weren't sure about the interface, so didn't want to commit on
any policy.
