gitian buildling on debian 9.5

gitian.md

Some changes are needed to build on debian because of the switch of the guest OS to bionic.

lxc that comes with debian is not high enough version to support bionic (the minimum is 2.1.1), so need to build from scratch.

debootstrap that comes with debian will give the following error:

    $ bin/make-base-vm --lxc --suite bionic --arch amd64                                                                                              
    E: No such script: /usr/share/debootstrap/scripts/bionic

dependencies for gitian buildling on debian 9.5:

    apt-get install autoconf automake pkg-config libcap-dev

    # get lxc 3.0.1
    git clone https://github.com/lxc/lxc.git
    cd lxc
    git checkout lxc-3.0.1
    ./autogen.sh
    ./configure
    sudo make install

    # get debootstrap
    wget http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_1.0.95.tar.gz
    tar -zxvf debootstrap_1.0.95.tar.gz
    cd debootstrap-1.0.95 
    sudo make install

• if you forget to install libcap-dev before building lxc, lxc-execute is going to fail because an essential program init.lxc.static is not built
