Blessedly, the rules are different for NFS because the server handles integrity.
I usefully mounted my Solaris home directory concurrently twice, once BINARY;
once with EBCDIC translation.

But the HFS mount map option UPPERCASE-NAME invites denial-of-service.
I might ( cd /u/FooBar ) and FOOBAR's home would remain mounted there
for a time and FOOBAR couldn't access it mapped as /u/foobar.

IBM addressed this with a mode that required the mountpoint to be entirely
lower case.

I thought that ASIS-NAME with DISABLE(DSNCHECK) would have been
a better approach.
