Example chunk (simplified commands):

    {
        "kind": "chunk",
        "configure-commands": [
            "mkdir o",
            "cd o && ../libc/configure --prefix=/usr"
        ],
        "build-commands": [
            "cd o && make"
        ],
        "install-commands": [
            "cd o && make install_root=\"$DESTDIR\" install"
        ]
    }

Example stratum:

    {
        "name": "foundation",
        "kind": "stratum",
        "chunks": [
            {
                "ref": "baserock/bootstrap",
                "build-depends": [],
            },
            {
                "repo": "linux",
                "ref": "baserock/morph",
                "build-depends": ["fhs-dirs"]
            },
            {
                "ref": "baserock/bootstrap",
                "build-depends": [
                  "linux-api-headers"
                ]

                "build-depends": [
                  "fhs-dirs",
                  "linux-api-headers"
                ]
