Even that is way too complicated and error-prone if you want to do large upgrades. Give me a "copy http://$image flash:" any day... It's not even overly hard to do that with a proper filesystem underneath *and* per-component upgrades - mount the image read-only, mount a read-write section of the flash on top of it (overlay), install all the hotfixes to the overlay, and if the underlay is upgraded, wipe the overlay at the next reboot. Done. Yes, there are scenarios where this is not as flexible as what XR offers today... but hey, I trade a bit of flexibility against extensive nightmares every day. gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.
