RebornOS is a distribution based on Arch Linux
It starts as an Antergos bifurcation, offering more options during its installation, based on the Antergos cnchi installer, using the latter's repository, and one of its own.
Once the development of Antergos is finished, RebornOS becomes an independent distribution, no longer depending on the Antergos repository, but on its own repository (besides, of course, the Arch Linux repositories).
It currently offers a cnchi-based installer, which works without problems, while developing its own installer: Fenix.
1) You can attempt to use the automated script for the appropriate Raspberry Pi model (additional models will be added over time).
2) You can do the installation manually:
Please follow the instructions from the ArchLinuxARM install page: https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4
Replace sdX in the following instructions with the device name for the SD card as it appears on your computer. Replace rpiX with the correct one (i.e. rpi4, rpi3, rpi2, rpi)
