Anyone have a "snapshots for dummies" link they can provide?

I’ve read through the btrfs wiki about snapshots and while I understand things (albeit at a pretty high level), when I start to play with it I encounter weird results or unexpected results (e.g. NFS automounts the .snapshots directories if the root is exported and “fun” ensues — see my issue experienced here).

I need one of those Snapshots for Dummies books :smiley:
