According to Richard Dawe:
> Below is a patch fixing bugs in the /dev/zero and /dev/full support.
> The bugs fixed are:
> 
> * open: Don't decide we're emulating until we've checked that /dev/zero
>   or /dev/full (as appropriate) have been installed.
> 
> * link: Don't allow linking to or from /dev/{zero,full}.

Why?

> * unlink: Check the filenames. If we're not trying to remove
>   /dev/{zero,full}, then pass it through.

This mean that "rm /dev/zero" can never be removed, right?

Does that mean that when somebody codes support for /dev/hda (e. g.)
he must add it to this list?


Right,
