If you like non-owners to have no unlink permission, you have to set the sticky bit. If you want other users not to be able to delete files you put into a public directory, put a link into that directory and keep one in a private directory. 2) If you're accounted for the space occupied by your directories, you need the permission to remove the directory. Otherwise you could DoS other users if you have write permission in one of his directories. -- Funny quotes: 29.
