SUIDDIR will work for any user EXCEPT ROOT
I did this because I felt it was a security hole to allow users to create
files owned by root.
(from memory it will also refuse to do files that have the execute bit set
but I can't remember for sure)
We use it all the time on our PC fileservers so that DOS users always own
the files in their dropbox directories but they can give each other files
(e.g. documents).

Nothing, they just can't be owned by root.
