Known issues:

  * Available space on devices with only 4MB flash is very low,
    users requiring extra packages might want to consider using the
    image builder to repack custom images

  * The available memory on devices with 32MB RAM might be too low to
    reliably run opkg or sysupgrade operations, especially in
    conjunction with LuCI

  * Any outstanding issues reported at https://bugs.lede-project.org/
