Indeed, Also dm devices from LVM, the md RAID paritions
and the ordinary hard drive partitions

What surprises me is the creation dates. I thought all these /dev
devices would be created at boot time, but the creation dates not all
the same.

I see July 24 for LVM's dm partitions, and August 10 for the physical
partitions and the RAID devices.

Auguset 10 might be when I did the security upgrade; July 24 might have
been when I last booted (because of a power failure).

Didn't there use to be something like by-path? That might distinguish
the devices connected directly from the motherboard from the ones
connected via an expaneion card.

(I made sure that the partitions cotributing to a RAID device were on
different adaptors -- one from the motherboard paired with oe from the
expansion card)
