This is horrible. I just screwed up my system by booting a kernel on this:
it worked beatifully, but due to other reasons I then wanted to bisect a
totally unrelated issue. While having _totally_ forgotten about this
issue, even if I was technically aware of it.
.. so I installed a new kernel, and now it won't boot due to "couldn't
mount because of unsupported optional features (1)". In fact, I have no
kernel available on that system that will boot, since my normal "safe"
fall-back kernels are all distro kernels that can't boot this either.
Ok, so I'll end up booting from a USB stick, and it will all work out in
the end, but this does essentially make it entirely impossible to do any
bisection on any btrfs system.
