This can cause execve to fail when it wouldn't on a real system. For example, the follwing command should not fail in the emulated environment: $ /bin/true $(yes | head -n 100000) -bash: /bin/true: Argument list too long To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1356916/+subscriptions
