Re: Introduction + interest in a riscv64 port of GNU Mach/Hurd

Hi,

Thank you for the quick replies and the pointers.
Hakan, thanks for the stub port — it's a solid foundation to build on.
I've cloned your fork and will be replacing the stubs with working
implementations step by step.
Samuel, I'll check the bugaevc/wip-aarch64 branch for the multiboot
approach.
I'll send small patches as I go rather than sitting on a large branch.

Best,
Diego
