+"Device independent" naming for devices.
+
+With a Fedora-based appliance, using libata driver, devices have
+"SCSI" names like /dev/sda.
+
+With an EPEL-based appliance, using old ide driver, devices have names
+like /dev/hda.
+
+If we use virtio_blk, devices will have names like /dev/vda.
+
+What a mess.
+
+So the idea would be to add a device independent naming scheme, such
+as the one used by grub:
+
+  "(hdX)"   X = 0 means 'a', X = 1 means 'b' and so on.
+  "(hdX,Y)" Device X, partition Y (in grub, this counts from 0 which is
+            deeply confusing).
+
+There would have to be a very simple rule.  If guestfsd was expecting
+a /dev block device or partition name, then the alternate form can be
+used, and we would just look it up using the normal output of
+guestfs_list_devices.
+
+Maybe best is to use /dev/sda as the "standard" naming.  That
+shouldn't cause conflicts in the appliance because we tightly control
+what drivers are available.
+
+Note there's a lot of hackery that currently exists in tests.c which
+could be *removed* if we made this change.
+
+Open: Should the substitution be done in the library layer or in the
+daemon?
