It is not only btrfs, but also swap. But the latter problem can be
solved easier. In addition, switching to 4k also enables 48bit VA,
which opens another can of worms.

Are we talking about 42.2 or tumbleweed ?  I'm sort of okay with doing
that for 42.2 when we document it properly and mayb ealso fix the swap
issue. Because I seriously hope not that many people are using btrfs.

For tumbleweed, I would only want to switch when we have sorted out
the remaining issues. And only because I am going to be hit by this
