Traditional chroot is with binfmt_misc. Debian and ubuntu packages of Qemu enable OC flags, so at least all debian/ubuntu users who use qemu linux-user in chroots are affected. Using OC seems quite typical: http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-emulation/qemu/files/qemu-binfmt.initd-r1?view=markup http://rwmj.wordpress.com/2013/12/22/how-to-run-aarch64-binaries-on-an-x86-64-host-using-qemu-userspace-emulation/#content Others, like Suse, scratchbox use the P flag and wrapper binary.
