Jack Wallen walks you thru the method of putting in and utilizing the brand new Kali Linux snapshot instrument.
Kali Linux is an absolute should for penetration testers and different varieties of admins seeking to preserve their techniques and networks as safe as doable. With tons of pentesting instruments pre-installed, this Linux distribution might simply be your one-stop store for auditing system safety.
Since you’ll be utilizing so many various (and highly effective) instruments, you would possibly take into account including the brand new snapshot instrument, Unkaputtbar into the combination. With this new system put in, you can at all times roll Kali Linux again to a working snapshot, ought to one thing go awry.
Now, earlier than I present you the best way to set up this new instrument, you need to have Kali Linux put in with the btrfs file system. That is completed through a handbook partition, the place you possibly can choose the file system for use (Determine A).
When you’ve put in Kali Linux with btrfs, you possibly can then add the snapshot instrument.
Let’s get it up and working.

What you’ll want
The one belongings you’ll must make this work are a working occasion of Kali Linux and a person with sudo privileges.
Easy methods to set up the required software program
The very first thing we’ll do is set up the required instruments to make this work. Log in to Kali Linux, open a terminal window, and concern the command:
sudo apt-get replace && sudo apt set up btrfs-progs snapper snapper-gui grub-btrfs -y
Subsequent, create the snapper configuration information for the basis system with the next two instructions:
sudo cp /usr/share/snapper/config-templates/default /and so forth/snapper/configs/root
sudo sed -i 's/^SNAPPER_CONFIGS=""/SNAPPER_CONFIGS="root"/' /and so forth/default/snapper
Subsequent we’ll forestall “updatedb” from indexing our snapshots (as this might dramatically sluggish the system down):
sudo sed -i '/# PRUNENAMES=/ a PRUNENAMES = ".snapshots"' /and so forth/updatedb.conf
Subsequent, we should configure our login handle to permit booting into read-only snapshots with:
sudo sed -i 's/^#user-authority-in-system-dir=false/user-authority-in-system-dir=true/' /and so forth/lightdm/lightdm.conf
Lastly, reboot for the modifications to take impact. When the boot display seems, you need to see Kali/GNU Linux Snapshots listed within the menu (Determine B).
Easy methods to create a snapshot
To create a brand new snapshot, concern the command:
The Snapper snapshot GUI will open, prepared so that you can create a snapshot (Determine C).
Click on New after which, when prompted (Determine D), give the snapshot a reputation and click on OK.
After you’ve created your snapshot, you possibly can reboot Kali Linux and, when the boot display seems, choose Kali/GNU Linux Snapshots. Within the ensuing window (Determine E), you possibly can choose and boot into the newly created snapshot.
And that’s all there may be to putting in and utilizing the brand new Kali Linux snapshot instrument. If that is your pen-testing platform of alternative, I extremely advocate making this addition as it would forestall catastrophe from hanging your OS, inflicting you to should re-install.
