I'm not sure about the following (should be easy to verify with
a clean installation of major distributions):

- Startup scripts, particularly for lockd.
- Properties of new knfsd. Might be a non-issue when knfsd is
        always the default. Think of:
        - knfsd cannot handle exported subdirs with different permissions
                such as "rw" versus "ro" (I believe) unless they are different
                [local] mounts on the server.
        - when exporting a locally mounted cdrom it is no longer
                possible to umount the cdrom until "exportfs -r" is issued
                once it has been mounted over NFS. knfsd keeps it busy.
        - [no]hide and other export options?

Maybe this has all been resolved or is a non-issue for other reasons (I
_really_ want the merge with 2.2.x) but just in case... my .1 cent.
