What do you mean exactly by “unable to get subdirectories”?

Image filesystems don’t have directories per-se, they have prefix namespaces though (which can appear to be subdirectories to a user).

For example, if you have a file spec like this:

/fubar/foo=foo

Then when you boot the target, it will appear that “foo” exists in a directory named “fubar” (but of course, there is actually not a physical directory “fubar” that exists on the filesystem).
