Yeah, I'm pretty conservative with zfs upgrades but have had no issues. The one thing I wish is that there were better documentation of grub compatibility. I have a root partition I haven't upgraded the features on because I have no idea whether it would break grub, and you can't reverse this. Sure, I have backups but I really don't want to deal with the hassle of restoring a filesystem over some feature I'd have to google to even know what it does. -- Rich
