Re: Mark module tun obsolete

[Paul Goyette <paul%whooppee.com@localhost>]

Hmmm, checking the cvs history it seems that I added this dummy module 
for a specific reason.  :)

Although creating an interface properly attempts to load the if_* module 
(if the device doesn't already exist), there's nothing that adds the 
prefix when one attempts to open /dev/tun;  the autoload code in specfs 
simply tries to load a module named tun.

Since _both_ methods of triggering the autoload need to work, we will 
need to have both modules.

So I won't be removing this after all.
