A new feature has been introduced recently for Kali Linux by Offensive Security, dubbed as Kali Unkaputtbar. This newly added feature offers the users of Kali Linux a new menu to boot directly into snapshots.
This new feature is available on all Kali Linux 2022.1 and on the later systems that by default utilize the Btrfs file system.
Here’s what the Offensive Security stated:-
“Have you ever wished you could travel back in time after deleting that important customer report or after installing a broken driver (Nvidia?) just before heading into a board meeting? Well, you better read on because now you can.”
Kali Unkaputtbar is a new feature that enables users to bring the snapshot feature of the virtual machines to the bare metal, and in some specific troublesome situations, this new feature could be very useful and make your system more buff by injecting some steroids.
