hadn't seen sanoid, very cool, my zfs tooling is still pretty bare and I'm generally using obnam for linux backups. I was planning on finding something for automatic zfs snapshots and I guess sanoid answers that question, thank you. Also very nice trick to put lib/lxd under zfs too, hadn't thought of it.
