services/qemu-binfmt: Use the F flag and the static output of QEMU.
Fixes <https://issues.guix.gnu.org/36117>. Before this change, the 'binfmt_misc' entries registered for QEMU would not be usable in container contexts outside of guix-daemon (without manually bind mounting file names). For example: $ docker run --rm arm32v7/debian true standard_init_linux.go:207: exec user process caused "no such file or directory" After this change, any container can make use of the QEMU binfmt_misc registrations, as their corresponding QEMU static binaries are fully pre-loaded by the kernel. * gnu/services/virtualization.scm (<qemu-platform>): Define using 'define-record-type*'. [flags]: New field, which defaults to "F" (fix binary). (%i386, %i486, %alpha, %arm, %armeb, %sparc, %sparc32plus, %ppc, %ppc64) (%ppc64le, %m68k, %mips, %mipsel, %mipsn32, %mipsn32el, %mips64, %mips64el) (%riscv32, %riscv64, %sh4, %sh4eb, %s390x, %aarch64, %hppa): Adjust. (qemu-binfmt-guix-chroot): Remove variable. (qemu-binfmt-service-type): Remove the qemu-binfmt-guix-chroot extension. * gnu/services/qemu-binfmt (qemu-platform->binfmt): Use the static output of QEMU. * doc/contributing.texi (Submitting Patches): Update doc. * doc/guix.texi (Virtualization Services): Update doc.
