I have used the various root-on-ZFS so I can supposedly make a snapshot.
Reading the man page for creating snapshots got me a bit confused.
Reading that, it seems to make a backup of a newly installed system, I need to take a snapshot twice. Because if I only took one snapshot (let's call it fresh) any changes I make will be reflected on fresh (that is: my snapshot grows in size as well).
Can someone please explain? Thank you.

as the data on the active dataset changes, the snapshot consumes more data than would otherwise be shared with the active dataset
