+====== Permissions ======
+  * For Wine to be able to use the ''STAGING_RT_PRIORITY_SERVER'' environment variable
+  * Allows ''rtprio'' up to ''94'' and ''nice'' up to ''10''
+  * May also allow Realtime priorities to be used with other applications
+  * :!: TODO: Apparently you can use a username instead of a group?
+  * :!: This has not been researched since 2019
+===== RT Priority Permissions =====
+  * :!: This makes the assumption that the current user is also part of a group with the same name ((2023: This is the case for Fedora 39, openSUSE TW, and Ubuntu 23.10))
+  * Verify groups with the ''groups'' command
