Given an unmodified CVS -- not necessarily the case for free OS'es --
renaming files and directories will always have /some/ downside.  You just
have to choose your poison.  I can't speak for FreeBSD, I don't know what
methods they use.

If I had free run of the GCC repository, I would copy old,v to new,v
directly, then in a checked-out tree, "cvs remove old" with a note pointing
to new.  That's simply the form of poison I find, well, least poisonous.
Messing about in the repo directly is highly discouraged under GCC, however.


For Subversion, renames and other such "metadata changes" are versioned
like everything else, and all this will be wonderfully moot.
