 Just to clarify: does it not have /dev or is /dev empty?

 Does it have tmpfs or mfs support in the kernel? If one of that is available
 and /dev exists, init should mount a ramdisk over /dev and populate it.

 And for the patch: MAKEDEVTARGET all sounds a bit heavy, most architectures
 use a special "minimal" or "ramdisk" target (i.e. to create opty entries,
 which are considered a security issue in non-install scenarios, but are
 more lightweight than offering ptyfs support).

 Dear Martin,

 Hello!

 >Just to clarify: does it not have /dev or is /dev empty?

 My expression might be bad.
 NetBSD/ofppc's ramdisk kernel doesn't have /dev/MAKEDEV.
 /dev is empty!

 >And for the patch: MAKEDEVTARGET all sounds a bit heavy

 My POWER3 is the fastest CPU in the world. ;-)
