But FF says I don't have perms, so I put it here and will move it when the perms are sorted. The current kernel its running, 4.4.4-rt9-v7+. has some warts vis-a-vis its local keyboard/mouse operations but is otherwise doing a fine job. copied to the pi, unzipping took a couple minutes, and now mc is slowly writing the unzipped contents of the file on that drive back to that drive. Did I mention that usb-2, pi version, is slow yet? 749 megs to write, its making 367 bytes a second. I may as well send this and go back to bed.
