Does having them installed under a different package name make it easier for
the user to downgrade?  Isn't the best-case downgrade process in both cases
going to be "uninstall the samba4 version of the package, manually massage
your config back into a usable state (or restore from backup), and install
the samba3 version"?  If so, I see no reason to not begin supporting direct
upgrades (and debugging them).

As long as we know samba will never reach 3.9.1 before it reaches 4.0, yes.

Steve Langasek                   Give me a lever long enough and a Free OS
Debian Developer                   to set it on, and I can move the world.
