Exactly. "cvs rtag" will tag the HEAD in the repository. I could check out
something from a year ago and then do a "cvs tag" and it will tag *that*
rather than the HEAD.

The whole point about "freezing the repository" is bogus, given how CVS
works. Personally, I never pushed because these "freezes" during the tag
have never impacted what I'm doing. But the myth of needing to "freeze"
really should stop.

That's what I was asking for.  Alright, if we know that it is safe, then I
would remove the freeze step.
