Provide a detailed description of the proposed feature

Add documentation about brew support for SELinux

https://github.com/Homebrew/brew/blob/fa9f8bd78142b8cdf30e640dd20efcd2a6caf60a/docs/Homebrew-on-Linux.md

What is the motivation for the feature?

The only proof it has on the internet currently is that Universal Blue ships it, and yet respects SELinux

It would be necessary to add a mention about it in the docs

How will the feature be relevant to at least 90% of Homebrew users?

This documentation would of course only be relevant for Linux users

What alternatives to the feature have been considered?

Not writing those docs line

What would the docs encompass? Because you can write many things about Homebrew and SELinux.

Acknowledging brew works [out of the box / or with added tweaks / or doesn't work] with SELinux would be a nice addition to the docs
