Package: qemu-user-static Version: 1:2.8+dfsg-6 Severity: wishlist Dear Maintainer,
Please consider enabling the "F" flag in the binfmt entries which this package adds. From https://www.kernel.org/doc/html/v4.12/admin-guide/binfmt-misc.html: F - fix binary The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn``t work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes. This is useful because it avoids the need to bind mount the qemu-user-static binaries into the container/chroot/whatever. The documentation entry appears to have been added in Linux v4.8-rc1 so I pressume the feature was present at some point before then and is in any case available in the 4.9 kernel used by Stretch, so enabling this in the Buster onwards versions of this package ought to be reasonable I think. I'm not sure if this also applies to the qemu-user-binfmt package, that's dynamically linked and I confess I'm not sure how that works WRT chroots and such.
