# Overview of SELinux
I added an overview of the SELinux subsystem, which is one of the popular MAC systems that are available on Linux. It's used mostly in the Red Hat world (Red Hat Linux, Fedora), but can also be found on other Linux distributions (also on Android). I was interested in the topic mostly due to the fact that Podman relies on SELinux when mounting volumes. Lack of any SELinux knowledge might lead to issues when containers try to access the mounted files. While learning about SELinux, I found it to be quite an interesting topic. You can see my gist of it here.
