Hey! Since 6.0, qemu-user-static does not seem to work properly through binfmt. I am a bit lost on how to diagnose that: 13:23 ❱ cat /proc/sys/fs/binfmt_misc/qemu-aarch64 enabled interpreter /usr/libexec/qemu-binfmt/aarch64-binfmt-P flags: POCF offset 0 magic 7f454c460201010000000000000000000200b700 mask ffffffffffffff00fffffffffffffffffeffffff 13:23 ❱ ./bin/busybox ls BusyBox v1.30.1 (Debian 1:1.30.1-7) multi-call binary.

[...] 13:25 ❱ file bin/busybox bin/busybox: ELF 64-bit LSB executable, ARM aarch64, version 1 (GNU/Linux), statically linked, BuildID[sha1]=6a67fd6d086c703062f3be2d751adf619aa67bc6, for GNU/Linux 3.7.0, stripped When invoked through binfmt, the binaries seem to go from "I display something wrong" to "I will wipe your entire home". That's what happened to me when using cowbuilder. The chroot was not able to be setup correctly and during the clean phase, cowbuilder did not detect the bind mount and/or was not able to undo them, rm -rfing everything that was mounted. Downgrading qemu-user-static to 1:5.2+dfsg-11 fixes the issue. 13:30 ❱ cat /proc/sys/fs/binfmt_misc/qemu-aarch64 enabled interpreter /usr/libexec/qemu-binfmt/aarch64-binfmt-P flags: POCF offset 0 magic 7f454c460201010000000000000000000200b700 mask ffffffffffffff00fffffffffffffffffeffffff 13:31 ❱ ./bin/busybox ls bin usr - -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (500, 'testing'), (101, 'experimental-debug'), (101, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.13.0-trunk-amd64 (SMP w/12 CPU threads) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled qemu-user-static depends on no packages.
