Never mind that problem.
Consider what happens if you reboot with a different CD in the drive!

I once fixed a filesystem to use different faked inode numbers every
time a filesystem was mounted.
Without that NFS clients would write to the wrong file in the wrong FS.

The 'impossible to get rid of' retries for hard mounts were something
up with which I had to put. (A preposition is something you should not
end a sentence with.)
