Anyone planning on ZFS or BTRFS for file systems?

@DrYak, thanks for the pointer to snapper, but it will be easy enough to modify my old ZFS snap shot utility. And snapper is not designed for alternate boot environments. I also modified my scrubber utility.

Now I have to decide, (though it will probably take me weeks), whether to use the whole eMMC, (except for "/boot" and swap), as BTRFS. Then control the sub-volumes for things like "/home", (which I would use my snapshot script).
