Sorry about that--I identified the files on the system using grep.

That's true. However, the naming scheme is not devfs-specific, and is
used by others.

Yes. The device naming scheme is independent of devfs.

The "correct" location is rather subjective. I use the alternate
scheme because I prefer it, and I'm not the only one to do so. The
udev devfs.rules scheme is in common use and supported by the udev
maintainer (who also uses it himself), and on such systems ybin and
mkofboot are broken. I also used the scheme without devfs or udev for
several years (but I've only recently moved to powerpc).
devfs-style device names are currently supported fairly
comprehensively throughout the whole Debian system.

Sure.
I may yet alter the nvsetenv patch to allow the nvram device to be
configurable at runtime, which would make this patch rather more
robust. I'll discuss that with the powerpc-utils maintainer first,
though.
