    I've not users this in quite a while, so I may be wrong here, but I think
    what you need is:

    rootfs_name="dlroot"

    If gzip support is compiled in, it will automatically try to fetch
    dlroot.gz first and if it succeeds, it will uncompress and use it. The
    way you have configured it, it tries dlroot.gz.gz, which fails, so then
    it tried to load dlroot.gz as an uncompressed file.
