• 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 makes the assumption that the current user is also part of a group with the same name ¹⁾
• Verify groups with the groups command
