I queried it less for what it does specifically than when it seems to
appear in my logs.  Note the scsi generic sg0 is attached well before sd
is attached to the device:

Now this may occur because we have sg in the initrd and just because it
is loaded.  Perhaps if we boot without it then things continue without
forcing a load.
