No. You do everything in the same directory. Tags in CVS are always
global (that's why we try to use "sandbox_USER" prefix to resolve
potential tag names conflicts).

If in doubt, set up a small repository with one file just on your machine
and run the procedure on it first (this is what I did):

    $ mkdir repo
    $ mkdir test
    $ export CVSROOT=3D`pwd`/repo
    $ cvs init
    $ cd test
    $ cat >test.cc <<END
    > line1
    > line2
    > line3
    END
    $ test
    $ cvs -d import -m '' test start kthulu
    N test/file.txt

    No conflicts created by this import

    $ cd ..
    $ rm -r test
    $ cvs -d co test
    cvs checkout: Updating test
    U test/file.txt
    $ cd test
    $ # edit file.txt
    $ commit
    cvs commit: Examining .
    Checking in file.txt;
    .../repo/test/file.txt,v  <--  file.txt
    new revision: 1.2; previous revision: 1.1
    done
    $ cd ..
    $ rm -r test

Now you have a repository with two revisions of the file. You may try the
procedure to revert the file to the first revision.

Hope this helps.

Best regards
Grzegorz
