Chainfire (the developer of SuperSU), has come up with a new style of rooting devices on Android 6.0 Marshmallow and above. This is "**systemless**" root, and is all the rage right now. So, just in case anyone feels curious, I thought there should be some information about "systemless" root here for future reference.

**The main question:**

What is "**systemless**" root, exactly?

This question has 2 ancillary questions, which are:

1. Where is it more applicable over traditional "**system-based**" root, and how is it different from it?

2. Is it better than traditional root? If so, how?

A comprehensive answer to the main question along with the ancillary questions will be preferred.
