SMUs were a good idea, but not really great in practice. Most customers I work with do not want to manage application level patches, just entire images, even in cases where they are just a process restart.
XR for a number of years now has had the concept of a “golden ISO”. It’s a single image either built by Cisco or customers can build their own that include the base software and the SMUs in a single image. You just issue a single “install replace myiso.iso” and that’s it.

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. 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.
