So what would you propose for Ubuntu?  Our default install doesn't
break things up like that.  Perhaps just for Ubuntu core?

That's what the previous UDS sessions discussed.  AFAICT from that
list the btrfs devs have fixed the issues identified.   I just
recovered from a power off btrfs bug myself, so I'm very happy to hear
they have a better test setup to reproduce those issues.

Thanks,
