it seems that the latest kernel update
linux-pine64-3.10.101-3-pine64-longsleep-50
is again missing xfs support.
Is there a way to go back to a previous kernel ?
XFS has been removed due to incompatibility - you can install Andy old kernel release at any time.
will support for xfs come back in a future release ?
Not in my 3.10 release - you can always build your own kernel if you do not need user namespaces.
