bash-4.2# ./containerd-stress density
INFO[0000] pulling docker.io/library/alpine:latest
INFO[0001] generating spec from image
rootfs absolute path is required

The error is thrown by functions WithImageConfig (density.go) ---> WithAdditionalGIDs (spec_opts.go)

if c.Snapshotter == "" && c.SnapshotKey == "" {
     if !isRootfsAbs(s.Root.Path) {
	  	return errors.New("rootfs absolute path is required")
     }
}

By default, this function populateDefaultUnixSpec will set the

	*s = Spec{
		Version: specs.Version,
		Root: &specs.Root{
			Path: defaultRootfsPath,
		},

defaultRootfsPath = "rootfs" in spec.go

It is obviously not an absolute path

I am very confused about this:

1. density test should never pass
2. WithImageConfig function is called in many tests in same way, like TestBindLowPortNonRoot in container_linux_test.go. they should not pass too
   I think both of two don't meet expectation.

test env:

centos 7
4.15.0-43.generic.x86_64

Please let me know if i make some wrong during the test
