Does that work?  CVS has a way of ignoring files with link count
greater than 1.

I use find, on the fly.  If there are new directories,

    $ find . -type d ! -name CVS -print | xargs cvs add

and ignore errors for directories that are already added.  For the files,

    $ find . -type d -name CVS -prune -o -type f -print |\
    > xargs cvs add

and also ignore double-add errors.

Are there any files in dir22/source, and if not, are you pruning empty
directories?  (the -P option).

cvs -nq update .

General impression:  you can have your development environment or you
can have CVS, and you can't have both.

Maybe you should treat your dev environment as a virtual vendor.
Export trees, not checkout, to use in development.  When ready,
import them back, not commit, into CVS, as if you were releasing
a tarball to yourself.  This is an extremely clumsy way to use CVS,
turning it into a glorified closet.  It also means that you develop
without the benefit of a source-controlled environment:  no cvs diff,
no cvs update, etc.
