Package: qemu-user-static Version: 1:2.10.0+dfsg-2 Severity: wishlist qemu-debootstrap's approach of copying the host emulation binary into the chroot is kind of messy. Nothing updates that binary when this package is upgraded. If the chroot is turned into a bootable disk image on the target hardware, the binary ought to be deleted, which is an added complication to deal with.
So I had an idea of moving the qemu static binaries into a subdirectory someplace. They could still be symlinked to /usr/bin/, but make the binfmt-misc paths use the subdirectory. Then that subdirectory could be bind mounted (readonly) into a chroot to make the binaries available inside it without copying them. Downside is that the bind mount would need to be set up on boot, or when the chroot is used, so the current copying might need to remain the default, and an option to do a cleaner bind mount added to qemu-debootstrap. (Of course, many user of chroots require mounting other stuff into them eg /proc, so this would just be one more thing to mount.) -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.13.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) qemu-user-static depends on no packages.
