I didn't fully get your last part? Do you mean you have not heard of BTRFS and snapper or what a bootable snapshot is?

Maybe in advance:

Snapper and BTRFS Snapper is a tool for Linux file system snapshot management. When used with BTRFS it can create bootable snapshots of your system including things like:

  • Kernel
  • Root filesystem (/usr, /etc, /var, etc.) These Bootable Snapshots then Show Up in Grub as bootable entries.

This is particularly useful for backup and recovery purposes. On openSUSE a snapshot is created everytime you run zypper (package manager) to install a package or update your system. It will exclude your home directory from the Snapshots. So changes made there are not rolled back in case you want to rollback to an older snapshot.
