If I were to design a devfs for this, the resulting device nodes would
become a directory tree, for the given case something like
sd0-+-cgd0-+-cgd0a-+-pv0-+-lv0
|-lv1
\-lv2
"Somehow" these nodes would be device nodes and directories at the same
time. That would be much nicer than having two nodes (with slightly
different names), one for the device node and one for the directory.
I don't think I've seen a devfs like that; there is a hierarchy in the
linux /sys/devices but it is determined by physical hardware attachment.
