MAKEDEV just provides a template for the correct devices. (One reason I don't believe in devfs is that it doesn't even create devices with the same names and attributes after N years of development, starting with /dev itself not having the permissions specified in /etc/mtree/BSD.root.dist.) > > - /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 should have commented out examples like most other rc files that don't have knobs in rc.conf, and it should have more than 1 example. If /dev/vga is actually non-optional, then it should be created by the driver and not by rc.devfs. Symlinks for devices should always be optional but this may be impractical for very old compatibility cruft like /dev/vga.
