The best way to avoid that is to use a statically linked qemu. > This patch solves this issue by passing the environment variables > with '-E' arguments to the child qemu instance.

Run ./scripts/checkpatch.pl on your patch... and add your Signed-off-by here. The environment is already managed in linux-user/main.c:main(), I don't understand why the qemu_execve() special case should differ from the general case. Thanks, Laurent
