ARM support?

[fsobolev]

Can ublue be used on an ARM (aarch64) device that can run regular Fedora?

[castrojo]

Not currently but hope to support it as soon as we figure out how. Some ARM-smart people have been reaching out to me so hopefully we can at least figure out what needs to be done.

Interesting that you should ask that @fsobolev, I was just talking to @castrojo about that. We are trying to sort an ARM resource for building. That's the easy part....

I've started work on this using ARM server resources donated by Equinix Metal. I hope to have builds of all the https://github.com/ublue-os/main images in archive in a week or so for testing with ARM!

We've produced a silverblue 38 image for testing. If you have an ARMv8 machine and can help verify the image rebases correctly please let us know: https://github.com/ublue-os/main/pkgs/container/silverblue-main/102915422?tag=38-aarch64

Hi, I wish to build bluefin ARM on my macbook pro/max. Could you share ARM build configs used to build ostree-unverified-registry:ghcr.io/ublue-os/silverblue-main:38-aarch64?

I think it's here: https://github.com/ublue-os/tarpit

One thing to note is most aarch64 systems have soldered flash storage, so it may be good to investigate ways to offload write intensive operations to tmpfs in RAM rather than trashing people's eMMC/SSDs every time they decide to rebase or get a few weeks behind on updates (or even during daily updates).

Also iirc aarch64 is not necessarily only armv8, as I think armv9 is out, but the aarch64 instruction set covers both.
