Configuration tasks performed during deployment

===============================================

Partition Table manipulation

----------------------------

During image deployment the last partiton is enlarged to use all

the available disk space. If SWAP property is present an extra

swap partition is also added.

File system Resize

------------------

This task enlarges the file system of the last partition to use

all the available partition space.

Swap partition configuration

----------------------------

If swap partition is added during the image deployment, the swap

partition is formated and a swap entry is added to the instance's

fstab.

SSH keys removal

----------------

All SSH keys found in the image are removed. For debian instance,

where the key creation is not perfored automatically, the keys

are recreated by this task.

Temporary disable Remote Desktop (RDP) connections

--------------------------------------------------

RDP connections are temporarily disabled during Windows

configuration. This is done because when sysprep runs, there is a

small time interval where the new password is not applied yet thus

allowing RDP connections which raises some security conserns.

Perform SELinux file system relabeling

--------------------------------------

For redhat-based images, since the instance's disk is modified

during deployment, a full SELinux file system relabeling needs to

be performed. This tasks triggers a full file system relabel at

the next boot.

Hostname or Computer name assignment

------------------------------------

The instance name is assigned as hostname (or Computer Name for

Windows instances).

Change password

---------------

This task will change the password for the users specified by

the USERS property.

File Injection

--------------

The files specified by the PERSONALITY image property are

injected into the instance's hard disk.
