I just tried the patch and ran the setup script with: ./scripts/qemu-binfmt-conf.sh --debian --qemu-path=/usr/bin --qemu- suffix=-static --preserve-arg0 yes and: root@nofan:~/qemu> systemctl restart binfmt-support.service root@nofan:~/qemu> But still don't get the correct path: (sid-m68k-sbuild)root@nofan:/# sh -c 'echo $0' /bin/sh (sid-m68k-sbuild)root@nofan:/# Do I need to do anything else? -- .''`.

The problem can be boiled down to qemu-user always reporting absolute paths for the shell variable $0 no matter on how the command was invoked. A simple reproducer is this: On normal system (no emulation): root@nofan:~> sh -c 'echo $0' sh root@nofan:~> On qemu-user: (sid-m68k-sbuild)root@nofan:/# sh -c 'echo $0' /bin/sh (sid-m68k-sbuild)root@nofan:/# > [1] https://lists.debian.org/debian-68k/2019/07/msg00007.html To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1835839/+subscriptions
