Devices


Mostly we can map to native device nodes
just ioctls need to be mapped
mutiple nodes can't map to the same dev_t!

Some cases need their own nodes:
STREAMS

Need to register an linux character device
has different dev_t from native one

Should we do dev_t remapping?
some envs (e.g. LKP) do
through special filesystem
no, I don't want to touch devfs
