Probably not okay, because yes, this will make full copies instead of
diffs in the version-controlled files.  One thing you can do is

1) First look for a pattern of files that should probably not be binary:

    cd <cvs checkout>

    find . -print | \
       grep -v '/CVS' | \
       egrep '/(regex1|regex2|regex3)$'

    Once you've verified that you have the correct pattern for
    selecting files, pipe that output into an "admin -kkv" command:

    find ... | grep ... | egrep ... | \
       xargs cvs admin -kkv

    After that you should be fine.  You can use -kkvl if you are
    concerned about who's locking the file.

Yes, there would have been a better way, and I wish more places
discussed this.

1) Initialize your repository:

   cvs -d /path/to/repos init

2) Modify CVS's default keyword handling based on filename:

   cvs -d /path/to/repos checkout CVSROOT
   cd CVSROOT
   <edit cvswrappers>

   In the cvswrappers file, you can specify that some files are binary
   by default.  These, for example, cover most of the worst offendors
   (delete leading spaces).  You probably have some others ...

   *.[Dd][Oo][Cc] -k 'b'
   *.[Gg][Ii][Ff] -k 'b'
   *.[Gg][Zz] -k 'b'
   *.[Jj][Pp][Ee][Gg] -k 'b'
   *.[Jj][Pp][Gg] -k 'b'
   *.[Pp][Dd][Ff] -k 'b'
   *.[Pp][Pp][Tt] -k 'b'
   *.[Pp][Ss] -k 'b'
   *.[Tt][Aa][Rr] -k 'b'
   *.[Tt][Gg][Zz] -k 'b'
   *.[Zz] -k 'b'

   Save the file and commit.  Subsequent commits or imports will be
   checked against this file.

   Optional:  clean up

   cd ..
   cvs -d /path/to/repos release -d CVSROOT

   I think what you want is something like this:

   cvs update -j HEAD -j INITIAL_RELEASE
   cvs commit
