Since abbc0ce ("qemu-binfmt-conf: use qemu-ARCH-binfmt"),
qemu-binfmt-conf.sh automatically replaces the default qemu binfmt wrapper
qemu-$ARCH with qemu-$ARCH-binfmt in order to ensure that argv[0] is
preserved; qemu-$ARCH-binfmt is a link to qemu-binfmt, which is just a
simple wrapper that mangles argv to achieve the desired result.
This is inconvenient in some situations. In particular for running
foreign-arch containers, it's useful to use the binfmt_misc "F" ("fix
binary") flag to pre-load the qemu wrapper in the kernel. That way,
foreign-arch containers can be run just like native containers, without
having to bind-mount interpreters into the container. But that's impossible
with the SUSE binfmt wrapper that needs to exec() a different (native)
executable.
As the qemu-binfmt-conf script supports the --qemu-suffix option anyway,
use it to set the "-binfmt" suffix, thus allowing admins to override the
SUSE default with the option "--qemu-suffix ''".
