I installed tuxmake into a virtualenv and tried running: $ tuxmake --runtime podman --target-arch arm64 --toolchain gcc-12 --kconfig https://storage.tuxsuite.com/public/linaro/lkft/builds/2StEPFnEfoD076PRu8fIxjexhnM/config , but after downloading some Docker stuff it died with the following error: Error: copying system image from manifest list: writing blob: adding layer with blob "sha256:faef57eae888cbe4a5613eca6741b5e48d768b83f6088858aee9a5a2834f8151": processing tar file(potentially insufficient UIDs or GIDs available in user namespace (requested 0:42 for /etc/gshadow): Check /etc/subuid and /etc/subgid if configured locally and run podman-system-migrate: lchown /etc/gshadow: invalid argument): exit status 1 I also tried building with the config you provided, but the resulting kernel didn't boot with my existing rootfs. The third attempt was to take a config that's known to work, and enable CONFIG_ARM64_64K_PAGES=y in it, and boot on a rootfs that's known to work, but it didn't boot either, claiming that "/sbin/init exists but couldn't execute it". Are there any additional requirements to rootfs related to 64k pages? Or maybe there's a system image somewhere at tuxsite.com that I can use?
