As long as we allow /dev.1 as shortcut for /dev1/bus1, we also have to
make sure that /dev1/dev2 works for /dev1/bus1/dev2/bus2 - as long as
there is only one child bus per device.
We auto-root a path not starting with '/' via convention "first
component is ID then" (I like that). We auto-complete a path ending
with a device when we want a bus (a bit too clever).
... only if there is a single child bus only (i.e. it isn't ambiguous).
Which is the common case though.
names in the middle is too clever by half!
Yea. I have to agree here. It can only work reliably if you make sure
all your devices have unique ids. In which case there is no need to
reference dev1 at all, you can just use the "first component is ID then"
mechanism for dev2.
