(rest redacted, my summary: the automatic guessing version is not to
your liking.)

How about:

UPGRADE_NOTICE+=	"<=4.5 Please foobar the nozzle before upgrading."
UPGRADE_NOTICE+=	"<=5 Please remove the baz before upgrading."

so that when you upgrade from a version before 4.5, both messages are
displayed and if you upgrade from a version before 5, the second is
displayed?

At least by pkgin. Not sure if we want to teach pkg_add about this and
how - it doesn't have any confirmations. Though we could theoretically
make these warnings something that needs a -y flag for pkg_add before
you can really update.

Similarly:

SUPERSEDES_NOTICE+=	"Please dump the database before the upgrade and restore it afterwards"

which is shown if a SUPERSEDES was used to install this package
instead of the one it replaces.

How does that sound?
