I'd also feel better if the ZFS experts could explain how those come to be set on a zpool as well. I'd settle for a good script that could be run as root (better It is explained in the zpool-features man page. would be not as root) that would take a filesystem that was created by makefs -t zfs and turn on these features after an zpool upgrade. Script attached. Maybe a little bit too verbose, but you can see which features are active directly, and which ones only enabled. It expects a zroot.img in the current directory and creates copies to zroot_num_featurename.img where it enables the features. In the beginning are some variables to adapt to pool/image name and destination directory.
