Thank you.

Glad to have you on board.  I do not follow the btrfs mailing list, only
test it once in a while. :)

Sad to hear that.  Is there any way we can work around it on the
FreedomBox side?

I hope we can get btrfs (or zfs) working out of the box with FreedomBox.
But if not, we can drop the '--roottype btrfs' from the vmdebootstrap
argument list and be back where we started.  The change is at least at
the moment not intrucive.  It will be intrusive if we start to use
snapshots and volume management, but we are not there yet.

Happy hacking
