Doing a snapshot of the base OS install in ZFS

[jbssm]

I'm about to make some big changes to my Proxmox installation (I'm going to try VGPU Unlock), and I would like to be able to revert back to my present state if something goes wrong.

Since I've installed Proxmox in a ZFS file system, is there any way to do what I want?

of course, that is one of the main features of zfs. Do a snapshot, change system, restore snapshot or delete snapshot, after.
