similar to issue #204

https://github.com/genuinetools/img/blob/013bb211567bb92374315affaf0ffa1787fb23c2/unpack.go#L24 maybe this line should be changed to true?

@zhangyoufu This sounds like #231 , I have fixed some runc issues in my fork. I have PRs pending. https://github.com/kekoav/img

@zhangyoufu With my fork, I was able do the following:

$ docker run --rm -it \
>     --security-opt seccomp=unconfined --security-opt apparmor=unconfined \
>     --entrypoint /bin/sh \
>     --workdir /tmp \
>     kekoav/img
/tmp $ img pull alpine

/tmp $ img unpack alpine
WARN[0000] Process sandbox is not available, consider unmasking procfs: mount: permission denied (are you root?) 
Successfully unpacked rootfs for alpine to: /tmp/rootfs

.      ..     bin    dev    etc    home   lib    media  mnt    opt    proc   root   run    sbin   srv    sys    tmp    usr    var

I do get a warning about procfs, but the unpack seems to work. This is likely fixed by #232 .

@kekoav It works for me. Thanks!
