> Shell command "rm" is really "mv" to trash with the expectation that the server will
at some point really delete the contents of trash. With the advent of permissions, a user
can "mv" folders that the user cannot "rm". The present trash feature as implemented would
allow the user to suborn the server into deleting a folder in violation of the permissions
model.
> A related issue is that if anybody can mv a folder to the trash anybody else can mv that
same folder from the trash. This may be contrary to the expectations of the user.
> What is a better model for trash?
