Thanks Kellen and Cascardo. Kellen, nice that you're willing to work on that - this is a long standing problem and that work would be definitely appreciated by the Ubuntu community, be it free users or the Ubuntu Advantage customers!
Cascardo, about your two risks: (a) Partially agree with that. I agree with the part of testing, definietly this is the big chunk of work here. But I disagree with the retrocompatibility claim: of course we need to enforce that, but it's not that difficult in the LTS->LTS+1 model. See, we have a small number of HWE kernel per LTS release, I guess 4 or 5 correct? We need to be sure the makedumpfile updates are compatible with them, and that's it. If I'm talking Focal and some makedumpfile update (unintentionally) breaks dumps for kernel 4.19 or prior, why should we care if that's an unsupported scenario? IMHO it's much better to ensure that every HWE kernel receives a proper functional makedumpfile update, instead of an overly cautious attitude with older/unsupported kernels. (b) I agree here, but I guess the effort of SRU exception/ LTS->LTS+1 model will only make it easier. Imagine if when Ubuntu version X is released the upstream makedumpfile is not handling well the recent kernel version used by X - so we could either fix (or report) the makedumpfile issue quickly (especially due to part (a) above, the improved testing). Then, once it's fixed either by Canonical or community, this could quickly be integrated through a fast process, a version bump for makedumpfile for example. In the end, I think testing is the key word here - the more serious and thorough tests makedumpfile has, the more confidence in such model we'd have. But hopefully with Kellen's effort this stops preventing a more proactive approach with makedumpfile from happening, by updating it before users report bugs (which has been happening since forever for this package).
