Subject: [PATCH] Update sfs_load.overlay: Workarounds for /etc, /run, and /var

The problem with symlink method for loading sfs modules on the fly on overlay is that files under /etc, /run, and /var where got read-only. To fix this issue simply exclude those folder when creating symlinks. Then perform copy of files of /etc, /run, and /var from sfs module to rootfs
