@jhx I've built a kernel and yeah, it's doable, but I needed to spend quite a lot of time researching and essay-and-error testing my builds (of course it needed some try to just boot! XD), and there's an absurd number of build options, so I was never sure I got that right. And then you have to maintain your kernel manually too... But worst case scenario you're right, it's still an option. :)
