Raw.xz missing for atomic variants

Hello, I wanted to install Kinoite on my RPI 3 but unfortunately all atomic variants only have .iso files and not a raw raw.xz file that I can use with arm-image-installer.

I’m pretty sure there was a raw file before so is there still a way I can download a RAW file ?

Or can I otherwise use an iso file ?

I don’t remember if there were RAW Atomic Desktops images and I personally don’t know if there are any currently. However, if you are familiar with bootable containers and image-builder, you can build your own. I did this with Silverblue and installed it on a Raspberry Pi 4 using instructions from the Fedora CoreOS docs to boot.

Although I haven’t tried it, it might be possible with ISO images as well. You can try Booting via EDK2 using Separate Firmware Disk Mode. You should probably also use Raspberry Pi 3 UEFI Firmware Images instead of the ones in the Fedora CoreOS docs.
