This particular thing is not a problem for having kernel 4.9 in Qubes repository by default, because it already contains u2mfn module in it - you don't need to compile anything when installing it. Are there any other reasons why this should be opt-in? I'm asking because currently we don't have a mechanism for doing it. Only an opt-out (you can change kernel version in VM properties, and also choose different default option for dom0 kernel in bootloader settings). So, if new kernel is for example incompatible with your hardware, you always have option to rollback. And I think (until convinced otherwise) inventing/implementing opt-in mechanism for this isn't justified. > Anyways, those are my thoughts.
