   8 # Running mythbackend as non-root requires you to ensure that audio/video
   9 # devices used for recording have suitable user permissions. One way
  10 # to achieve this is to modify existing or create new udev rules which
  11 # assign these devices to a non-root group with rw permissions and add
  12 # your mythbackend user to that group. Be aware that console.perms can
  13 # also affect device permissions and may need additional configuration.
  14 # Running as non-root may also introduce increased process latency.
