The vfs storage driver currently shells out to the `cp` binary on the host system to perform an 'archive' copy of the base image to a new directory. The archive option preserves the modified time of the files which are created but there was an issue where it was unable to preserve the modified time of copied symbolic links on some host systems with an outdated version of `cp`. This change no longer relies on the host system implementation and instead utilizes the `CopyWithTar` function found in `pkg/archive` which is used to copy from source to destination directory using a Tar archive, which should correctly preserve file attributes.
