Hi Fedora community, Fedora on RPI is AMAZING and I'm working on a project to automate provisioning for a Raspberry Pi cluster. This would add a ton of CI capabilities and convenience. It would also take the edge of the nuisance that RPIs eat SD cards like I eat Oreos. Right now the process is pretty manual:
1. Put SD card in secondary machine 2. DD Fedora's minimal aarch64 image onto SD card 3. Grow partition 4. Put SD card back 5. Boot 6. Go through initial setup 7. Update all packages 8. Continue with regular config and host management This requires being physically in front of the RPIs (and provisioning machine) and involves a lot of hand holding. I'd like to make this process as headless as possible so that re-kicking a RPI is as easy as "setting a flag", rebooting and waiting for the RPI to come back up freshly installed. Right now I have the following path in mind how this could potentially work: The network interface of the RPI3B+ is capable of PXE booting, yay! So I'm thinking something along the lines of: 1. DHCP 2. Load files through TFTP (bootcode.bin -> start_x.elf -> DTB(?) -> u-boot.bin/IPXE -> kernel -> initramfs) 3. Boot kernel/initramfs which fires up Anaconda 4. Install Fedora normally 5. Use %post to copy device tree files to /boot and do other things necessary to make the RPI boot If this worked, provisioning would be as easy as: (0. Create DHCP reservation) 1. SD card into RPI 2. Turn on RPI 3. Login via SSH/VNC/etc. I managed to boot U-Boot, chain load iPXE (probably not necessary since U-Boot is capable enough) but when pulling the regular aarch64 vmlinuz/initrd.gz pxeboot images it just errors out with an error saying "Invalid application". My knowledge about the kernel/initramfs chain gets blurry here which is why all tries in altering the initrd.gz image have failed gloriously. If we can make this possible I'd be happy to turn it into a Wiki page so that others can extend their RPI environment with unattended provisioning. Happy memorial to everyone celebrating and thank you for your interest!
