I have toyed with putting ARM Archlinux on RPI4 with USB SSD booting for a while. It’s very hard with many steps. Just found out about EndeavourOS for Arm and it’s trivial to install by comparison. Thanks to all those who developed this.
Jim, thank you for the feedback.
Installing ARM for RPi 4b will be even easier in a few days.

Don’t worry, if possible the old method will be maintained. In fact, we may call upon you to do a test PineBook Pro install.

No make work for your self , this direction Endeavouros go

I can also can make pinebook pro test installs 
but I also don’t know if anyone else in the EOS forum uses the pinebook pro.
