Reading the article I’m not sure why I should t use ZFS on a boot drive. The author does, and was able to set up a nice incremental (encrypted) backup solution that was able to get them back up and running relatively quickly.

Only thing I can think is the manual nature of it maybe? I don’t see how btrfs would be better here based on the article unless I missed something perhaps?

I think the Creative Commons would fail to apply to the source material, but using the source material should be fair use in almost every context on Lemmy.
