Ask Sistina!  Erhm...  Heck, I guess this is Red Hat now :-)

IMHO it should scan /proc/mdstat or something equivalent to exclude
raid members.  Other than that, I think scanning as many devices as it
can is actually an improvement, even though it will often result in
ugly error messages when it attempts to scan say the CD drive and
there isn't anything there :-)

Well... Either you scan all devices that could possibly name
physical volumes, or you risk missing some.  What do you suggest?
Maybe a config file that enables you to limit the set of devices it
scans?  Well...  Seems to have already been done :-)
