hello!
see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=21ca59b365c0 linux 6.7 support use binfmt_misc to add new binary formats within unprivileged namespaces, I think this improves guix reproducibility and also avoids leakage of the host's binfmt into the compilation environment, improves the cross-compilation environment, and potentially unlocks more features, such as not having to system-configure qemu-binfmt, running x86-64 software on a riscv64 machine using `guix pack', guix shell -C -s riscv64-linux, etc.
