Thanks for the PR.

I'd like to see firecracker installed as firecracker, with a default path of /usr/local/bin

This is how I install it presently:

install_firecracker() {
    if ! [ -e /usr/local/bin/firecracker ] ; then 
        curl -L -S -f -o /tmp/firecracker.tgz https://github.com/firecracker-microvm/firecracker/releases/download/v$FIRECRACKER_VER/firecracker-v$FIRECRACKER_VER-$ARCH.tgz
        if [ $? -ne 0 ]; then
            echo "Failed to download firecracker"
            exit 1
        fi
        sudo tar -xvf /tmp/firecracker.tgz -C /usr/local/bin/ --strip-components=1
        sudo mv /usr/local/bin/{firecracker-v$FIRECRACKER_VER-$ARCH,firecracker}
        sudo mv /usr/local/bin/{jailer-v$FIRECRACKER_VER-$ARCH,jailer}
        sudo mv /usr/local/bin/{seccompiler-bin-v$FIRECRACKER_VER-$ARCH,seccompiler-bin}
        sudo mv /usr/local/bin/{seccomp-filter-v$FIRECRACKER_VER-$ARCH.json,seccomp-filter.json}
    fi

}

Looking forward to getting this in. I've left a couple of notes.

[alexellis]

Would we benefit from a defer os.Remove/Dir(tempUnpackPath)?

[richardcase]

Yes i think you are right.

[alexellis]

Perhaps you could do that in the next app you contribute? @Shikachuu is covering containerd but the rest are fair game.

Node should be fairly similar to add?
