I'm testing this build on Raspberry Pi 3B+.
Bug #1:
System Tools and Raspberry Pi Tools have a dependency on os.libreelec.tv marked as "Not available". This is minor and does not prevent install.
Bug #2:
mc from System Tools shows this error and the display is corrupted. Options / Display Bits is set to 7bit ASCII and can't be changed. Changes are not remembered. Other options are not affected - they are remembered.
Warning: cannot open /usr/lib/mc/extfs.d directory
