* Split code from freebsd.py to bsd.py
 * Make {Open,Net,Free}bsd classes inherit from Bsd

Otherwise kamaki complains

This can be used to display the current execution log.

Instead of defining a list member inside.

output is a Output class method and using it in _Progress makes the
code more confusing.

The user may alter the list of sensitive userdata

The type for those parameters is list:<type>

This can be used to define scripts to run on the guest media after
mounting it under a directory in the host.

This resolves #13, resolves #14 and resolves #15

Only use the mount feature in the Image class if it is supported by
the libguestfs build. The feature of mounting an image locally through
FUSE was added in libguestfs 1.18.

Fix a bug where the temporary file that would store the fatal error
in snf-image-creator is not deleted on normal exit.

Mount the image on the host system using FUSE and libguestfs.

This option can be used to display the detected metadata of an image.

Fill the GUI metadata with the detected info.

Order the arguments alphabetically.

When we cleanup all the changes made before booting the Windows VM, only
revert the /Microsoft/Windows/CurrentVersion/WindowsUpdate/Auto Update'
changes if the image has not been syspreped. Those values get deleted
during Sysprep.

Before booting the Windows VM either to install the VirtIO drivers
or to perform the various system preparation tasks, make sure that
the Windows Update is disabled. If it wakes up it can screw things
up.

This is a helper function used to remove common code found in

The SORTORDER is computed like this: ODDHHLL
O: OS type
D: Distribution
H: Version high
L: Version low

Fill the KERNEL image property with the version of the latest installed
kernel found in the input media.

This is automatically assigned according to the OS type and the
distribution of the image.

This resolves #9

When working with the dialog-based version of the program and a fatal
error occurs, create a temporary log file and put the full output of the
program there. This makes it easier for the user to determine what went
wrong.

Bump version to 0.7.4next

If qemu-nbd is not present at the host system, only accept raw images
as input media. This is a workaround for ancient systems like CentOS 6.x
where the nbd module is not compiled in the default kernel and the qemu
package does not include the qemu-nbd executable.

Do not use qcow2 to snapshot images that are raw. qemu-nbd is not
present in some old systems like CentOS 6.x. All we can do to support
those systems is to use the device mapper in as many cases as possible.

This complies better with the python conventions
