when default value is list or dict the default arguments are
instantiated as objects at the time of definition. This is significant
(exposing visible semantics) when the object is mutable. There’s no way
of re-binding that default argument name in the function’s closure. When
function is executed multiple times with its default value the value
will change between executions, possibly leading to strange side effects.

The lorax-composer program will launch a BDCS compatible API server
using Flask and Gevent. Currently this is a skeleton application with
only one active route (/api/v0/status).
The API code lives in ./src/pylorax/api/v0.py with related code in other
pylorax/api/* modules.
This reduces the amount of code in livemedia-creator to the cmdline
parsing and calling of the installer functions. Moving them into other
modules will allow them to be used by other projects, like the
lorax-composer API server.
It appears that sometimes the loop device doesn't get setup properly,
this may be a race with other users of loop devices on the system, or
some other mechanism that isn't understood.
To try and prevent total failure when this happens this patch retries
the loop setup 3 times before giving up. Previously it would wait for
the loop device to appear (checking 5 times), that operation is now
executed 3 times with a new losetup attempt each time.

This requires OVMF to be setup on the system, and for the kickstart to
create a /boot/efi/ partition. You can then use it to create UEFI
bootable partitioned disk images.
The UEFI firmware needs to be installed manually on the system, either
in the default location of /usr/share/OVMF/ or use --ovmf-path to point
to the location.

Use it to override the default dracut arguments (displayed as part of
the --help output). If you want to extend the default arguments they
all need to be passed in on the cmdline as well. eg.
--dracut-arg='--xz' --dracut-arg='--install /.buildstamp' ...

This can't be done the same way as on master because there is no rpm
database inside the installroot to run rpm -qa against. Do it at the end
of the yum transaction.

This uses the --release value as the yum releasever so that $releasever
in a --repo will work.
It also turns on assumeyes so that any gpgkey entries in the .repo file
will be installed and used automatically if gpgcheck is enabled for the
repo.
