Oh, well, now that you say it I remember that remotely from "Unix school". 
I'd completely phased that out.

Is there a way to achieve different behavior without using acl extensions? 
My objective is that I want users *not* to be able to delete certain 
files/directories in their home directories. It seems I can achieve this 
partly by putting files in a directory they don't own. They then cannot 
delete the files in the directory and therefore cannot delete the 
directory. As soon as the directory is empty they can delete it.
