Add binfmt_misc workaround detector to builds This is a recently introduced Linux Kernel feature that gives people like Debian package mantainers the power to arbitrarily redefine how executables are interpreted by the kernel. If your system gets tuned this way and you're not able to disable it, then you need to restore default behavior for the APE MZqFpD prefix as follows: sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register" This prefix will cover all .com executables built with this tooling. Please don't run the above command unless you're certain you need it. See #2 for additional context. 2020-08-31 19:31:11 -07:00			`#!/bin/sh`
