I really do like XR, but the update hassles...  so having an "image based"
XR ("scp $new_xr.bin router:", "boot system flash $new_xr.bin", "reload")
would have been really nice.

Now, SMUs and "restart only the affected service" is a great promise, but
in all our time with the ASR9001, all we've seen is "reboot required"
or "the SMU is not compatible with using service packs".  So, "just upload
a new image, and then reload" would have had the same effect, with less
argueing with the box.

Not sure XR64 is better in that regard, no experience - we lost trust in
Cisco before the question of "successor to the 9001?  something with XR64?"
arose.
