[Linux-disciples] Re: Deleting files you don't own

[Stephen R Laniel]

Related to the why-can-users-delete-files-they-don't-own
question, here's one I've had for a while but have -- I
believe -- never posed to this group of people: why are the
Unix permissions so limited? E.g., why can't one set
permissions to allow or deny

* deleting a file
* changing the permissions on a file
* modifying a file
* creating a file
* etc.

? I gather that AFS and other such beefy filesystems do
allow this, but I'm surprised that everyday Unix does not.
As I recall, WinNT has a rather extensive set of permissions
that one can set on every file.

Any idea?
