Personally I prefer to keep directories minimal until such time as there
is a need for more. As it is we're only talking about a handful of files
which are still easily filtered. Still, this isn't a huge deal. I care
more about the granularity of the setup. I feel having the usb/base bit
adds unnecessarily to the file count.

Otherwise I'm content-ish.
