A chroot environment provides you with isolation for testing in Linux. You do not need to take the hassle of creating a virtual machine. Instead, if you want to test an application or something else, create a chroot environment that allows you to select a different root directory.
So, with chroot, you get to test stuff without giving the application access to the rest of the system. Any application you install or anything you try gets confined to that directory and does not affect the functioning of your operating system.
Chroot has its perks, which is why it is a convenient way to test things for various users (especially system administrators).
Unfortunately, all of this works via the Linux terminal. What if you can have a graphical user interface to make things a little easy? That’s where “Atoms” comes in.
