    Is 3.2Mb a typical kernel size for small systems? It sounds large.

    0.24 seconds booting speedup sounds pretty thin. Adding a new
    decompression format will introduce more configuration/build/deployment
    complexities. How do we justify this?

    Did anyone look into just speeding up the gzip decompressor?

    What is this STATIC thing for?
