At least for BTRFS, "native" seems to be a bad thing. The BTRFS version that comes
with el7 is quite behind the current development version and unlike the "non-native" ZFS,
BTRFS is not packaged for easy installation into "my" linux. I guess I could run el7
with a "non-native" kernel. (but how is that better than running "non-native" ZFS).

In practice, it looks like the "dkms" stuff is junk (*for me*, it always breaks
between kernel releases - the problem it was supposed to solve).

But the "kmod" release of ZFS seems to work well enough. I do have to disable automatic
kernel updates, but that may be wise in some configurations anyway, YMMV.
