I think that's more a question for the livepatch people to be honest -
it's not entirely a technical one, there's a bunch of confidence level
stuff going on. For example there was some suggestion that people might
insist on having objtool support, though there's also substantial
pushback on making objtool a requirement for anything from other
quarters. I was hoping that posting that patch would provoke some
discussion about what exactly is needed but that's not happened thus
far.
