My (current) idea is to expose all devices as perm 0000, then let
devfs promote those nodes. As joerg said, this is kind of mtree(8),
- it should use well-established syntax
- it calls mknod(2) internally
It's not like mtree(8) in that:
- it can't hard-code paths.
We'll probably end up with some patterns, but let's not re-invent a new syntax.
