This approach may be a little hacked, but it works for now and
if it breaks at some point in the future because of e.g. circular references
that bridge will have to be crossed then
We can now press Ctrl+C remotely while any subprocess of the bootstrapping process is running,
previously SIGINTs weren't propagated to the bootstrapping process because there was a thread
in between it all. Now the bootstrapping process is in it's own process group.
The work consists of three parts:
* Allow for bootstrapping remotely,
this makes it possible to run the tests
on e.g. OSX with VirtualBox installed
* Make bootstrapping a fully automated process
where the manifests can be generated by the tests
and the tests can call the bootstrapper directly in python
* Create a framework wherein instances can be booted up
using the bootstrapped images and subsequently tested
It controls whether to include the 'deb-src' lines in image's
source.list.
Currently they are always included. This patch changes this
behavior by not including them by default; the user must set
this new config to true in order to include them.
This saves a bit of bandwidth in default installations. Also,
the use of src packages is not so usual in ordinary installations.
This is to allow building an image for a 64bit machine but with 32bit userspace.
Probably not a common usecase but ideal if you need to address more higher quantities of memory but cant migrate to a full 64bit userspace due to something like ruby eating twice as much memory.
Make sure it's either `auto' (the default), `always' or `never'. If it
does not match any of the values, raise a Docopt exception that causes
it to print usage and exit.
Tested:
- $ sudo ./bootstrap-vz --color=invalid manifests/gce.manifest.yml
Value of --color must be one of auto, always or never.
Usage: bootstrap-vz [options] MANIFEST

Mimic the behavior of the --color=<auto|always|never> found in tools
like `ls' and `grep'. Default to `auto' which checks whether stderr is a
tty to define whether colors are used.
Tested:
- Ran ./boostrap-vz --color=never and --color=always, confirmed
colorization worked as expected.
- Ran ./boostrap-vz --color=auto ${manifest_file} 2>bootstrap.log,
confirmed colors were not added to boostrap.log by default, repeated
the test with --color=always and confirmed escape sequences were
output.
