Hello, With this patch the bare-hurd64.tmpl os crossbuilds and runs on core-packages-team. Haven't figured out how to make a proper 64bit childhurd to get the native packages building with the nice offloading setup. I also managed to get the updated rumpkernel to build (the updated build.sh unsets C_INCLUDE_PATH, it also it depends on the new hurd lib libirqhelp which introduces a circular depency, for now i have created a separate package for it similar to hurd-minimal) . However idk if this is something for core-packages-team? I guess it should be hurd-team but that has moved into core-packages-team?
