Cool, thanks for filing this! I don't think we're quite ready to do this (since Fedora itself doesn't officially build for RISC-V yet), but I'm also excited for it.

Have you been able to get a minimal FCOS compose built with e.g. the RPMs at http://fedora.riscv.rocks/koji/?

Hi ! :-)

I have been able to build all the packages but two :

• moby-engine
• criu

I see however that http://fedora.riscv.rocks/koji/buildinfo?buildID=245364 passed a few weeks ago, so I guess I can continue to rebuild it.

About criu, the RISCV development is underway, but I wonder if we can skip this dependency.

The tests and experiments were reported here :

• https://risc-v-machines.readthedocs.io/en/latest/
• https://riscvera.com/

I have to present all my tests and packages to patch. I have to sync with https://twitter.com/dustymabe on IRC asap.

I have a base container of fedora for riscv64 that runs ! https://risc-v-machines.readthedocs.io/en/latest/linux/f33-scratch/

I can update it to the latest fedora 38/39.
