It does (actually, it scans /sys/block.)  It just didn't in test1. :)

I talked with the lvm2 guys when I set up my own initial LVM-on-root
FC2-test1 box and encountered the same behaviour.  So they came up
with...

        Log:
        Sysfs block device filtering option for 2.6.

...a patch to use 2.6's /sys/block pseudo-filesystem to filter which
block devices are worth probing for physical volumes.  This should
improve things no end.

That patch is in CVS on sources.redhat.com/lvm2 now, and I'll push it
into rawhide.  There will probably be a numbered lvm2 release with this
patch some time next week.

Cheers,
 Stephen
