The bit I read on Linux devfs I read made it completely broken (the driver
has to supply the data area for every device it might have...)
I have thought of doing it - but don't have the time.
The plan was to copy kernfs - but make the drivers give skeleton
information for complete sets of entries. So that items can exist is you
try to open them, but 'ls' will only show things that it is sane to open.
Also need to read a file to get non-driver entries and local permission
