 This leaves about 10 bugs in the 2 (now 4) devfs-specific lines in
 this file:
 
 - rc files should not create anything unless configured to do so.  They
   especially shouldn't delete correct links unconditionally.  (The
   correct link is created by MAKEDEV; it is vga -> ttyv0, not vga ->
   /dev/ttyv0.)
 - /dev/vga is compatibilty cruft for a 1993ish version of X (but I think
   current X's still use it because of their own compatibility cruft).  It
   is an especially bad example to put in a file with only 1 example.
 - [... comments about style bugs deleted]
