It should have been changed in commit 696deeec

Do not send through the monitor pipe the error messages. They may
contain internal sensitive information. Create a new report_error
function for sending errors through the monitoring pipe.

Conflicts:
	snf-image-host/create
	snf-image-host/snf-image-update-helper.in

Check if the users stated in the USERS image property do actually
exist.

snf-image-update-helper should check when creating a helper VM if
an snf-image-helper package was installed from an apt repository
through multistrap. If this is the case, snf-image-update-helper
should not complain about not finding the HELPER_PKG.

By default this directory is $(LOCALSTATEDIR)/cache/snf-image/helper

This is done for security reasons. The options may contain sensitive
data like the Pithos DB password and while the program (pithcat) is
running the whole command line is exposed to everyone through ps.

Hundred of warnings like this: `WARN: While quoting value for
'<registry_key>', warning returned: Data could not be interpreted,
quoting raw buffer.' are outputed when reglookup reads the registry
of a Windows 2012 system.

When snf-image-update-helper runned, it moved the kernel and the
initrd file out of the helper VM image. With this patch,
snf-image-update-helper will copy the kernel to the host without
removing it from the image.

You can disable this behaviour by defining the DO_SYNC image property.

If snf-image-update-helper exits with errors, delete the temporary
image file from /var/lib/snf-image/helper.

multistrap is more flexible allows as to define more that one
repository to retrieve packages from.

the kernel and init paths computed by snf-image-update-helper script
were incorrect.

Make snf-image-helper ran as init process when calling the helper
VM. Also make the helper VM shut down quickly by using the shut off
SysRq.

if this is set, then snf-image will run in debug mode.

Drop the rule that resets the password for user with username `user'
if the USERS image property is missing and the system is detected
to be a Fedora or a Ubuntu Linux system.

The curl dependency is not optional any more.

This url points to a json file that contains the value for other
OS parameters. Using this file we can pass parameters to snf-image
without writting them in Ganeti's config.data. This is
useful, for 2 reasons:
* Privacy: We don't want the password to appear in the Ganeti config
* Speed: Some parameters like IMG_PERSONALITY can be quite large (a few
KB) and since ganeti shares the instance configuration among different
nodes, the overall system will start getting slower if many instances
with IMG_PERSONALITY exist.

When a users inject a file in an image that already exists,
we want to make sure that this file is not altered by any other task.
So, the EnforcePersonality task, is the last task that should run
before the image is unmounted.

This backend type can be used if we want snf-image to configure the
VM disk without first copying an image to it. This is useful for
cases were the VM disk is already populated before snf-image runs.

Newer arch linux systems use this file to assign a hostname. If the
file is present and not empty, then use it.

 * Fix distro detection code to detect arch linux systems
 * Fix AssighHostname hook to successfully assign the host name on
   arch linux systems

This program is used to output info and error messages from the host.

This programm will get the stderr file as input and it will create a
json image-error msg

snf-image-host can output info messages using the log_info function.

Change msg field to messages in monitoring messages with type
image-helper and subtype error or warning. The new field is a list
of strings.

Change sys.stdin.readline with os.read
