Another data point:

In Erich's defense, I'd say his interpretation is quite understandable.
"...use only tag=. for the ports-* collections" also left me with the
distinct impression (some many moons in the past) that there are no
other meaningful (or safe) tags when csup'ing the Ports tree.

In 12 years of using FreeBSD I've never really sought out Erich's use
case (viz. roll back /usr/ports to some past known-good version), I
just assumed it wasn't possible. So this thread has taught at least one
person (me) a new thing -- I never fully grokked that adding "date="
to the supfile could achieve this desired result when csup'ing the
Ports tree. Now I know, and I've changed the Subject line of this email
in the hope it helps some future soul googling for the answer.

cheers,
gja
