Build kernel using vagrant

Using vagrant box(es) to build kernel

#WIP

# Use ansible/contrib/inventory/vagrant.py
ansible stretch -i ./vagrant.py -m ping

Check out the upstream Linux Kernel source code to here. It will appear as /vagrant/linux inside the vagrant machine.

Example workflow:

$ vagrant up bionic
$ vagrant ssh -c "KERNEL_SRC=/vagrant/linux BUILD_OUTPUT=/vagrant/build /vagrant/build_kernel.sh"

Update: Using virtualbox shared filesystem does not work. It does not support mmap calls, which are used by the tool-chains in compiling the kernel.

Alternative approaches:

• Use a custom vagrant box that has big enough partition (the default image is 20GB) to store the checkout git source code and output build. A 32GB filesystem should be sufficient for now.
• The host machine provides 32GB of RAM to the vagrant box. Then we can mount a tmpfs with the size about 27GB to store the checked out source and output objects.

The built .deb packages are at CWD.
