ssconf will become write-only from ganeti-masterd's point of view,therefore all settings in there need to go into the main configurationfile.

Extend DRBD disks with shared secret attribute
This patch, which is similar to r1679 (Extend DRBD disks with minorsattribute), extends the logical and physical id of the DRBD disks with ashared secret attribute. This is generated at disk creation time and...
Add serial_no attributes to objects
This patch adds the ‘serial_no’ attribute to the other top-level objects(the configuration object itself, the nodes and the instances).

Extend DRBD disks with minors attribute
This patch converts the DRBD disks to contain also a minor (per eachnode) attribute. This minor is not yet used and is always initializedwith None, so the patch does not have any real-world impact - except forautomatically upgrading config files (it adds the minors as None, None)....

Allow disk object to set their own physical ID
Currently, the way to customize a DRBD disk from (node name 1, node name2, port) to (ip1, port, ip2, port) is to use the ConfigWriter methodSetDiskID. However, since this needs a ConfigWriter object, it can be...
Add method to update a disk object size
This patch adds a method that implements updating of a disk(object.Disk) size, together with its children.
While this will not track the exact disk size, it allows at least anapproximate size to be recorded in the configuration (and queried)....
Complete removal of md/drbd 0.7 code
This patch removes the last of the md and drbd 0.7 code. Cluster whichhave the old device types will be broken if they have this applied.

Abstract the json functions into a separate module
This simple patch adds a new module that holds the simplejson functionsfor serialization/deserialization. This reduces the amount of redundantcode.
The patch also adds some normalizations to the json output:...
Modify Disk.GetNodes() to support LD_FILE
Codestyle fixes: adding a few empty lines
Add boot_order entry to Instance object.
First step to support custom boot device order for HVM instances, add alocation to actually store that information for the instance.
Add kernel/initrd paths to the instance object
This patch adds two new attributes to the instance object: - kernel_path - object_path
The code ignores them and the configuration handling is not broken bythis addition.
Add instance port support.
Extends the instance object by adding a port item, also adds changesto print this port via gnt-instance info.
Allow DRBD8 operation without backing storage
This patch adds the following functionality: - DRBD8 devices can assemble without local storage (done by allowing None in the list of children, and making DRBD8 to ignore all children if any is None)...
Add a support function to objects.Disk
This patch adds a function returning the device path if it is computablefrom the disk object (and we don't need to instantiate a bdev object onthe target node in order to compute this). Only LVs support this.
Create OS from an InvalidOS error

I forgot a pair of parentheses in that revision which break the commoncase. This patch adds them.
Fix printing of unconfigured DRBD devices
If the device is unconfigured (not yet did SetDiskID for it ever), itmight have a physical_id of None. This patch fixes that case.
Add a custom str() method for objects.Disk
This is done in order to easy debugging of disk-related issues.
Initial implementation of drbd8 template type
This is a partially working drbd8 template type. It does: - add/remove - startup/failover/shutdown

Remove the shebang from modules
Since modules are not directly executables, remove the shebang fromthem. This helps with lintian warnings.

Change class hierarchy in objects.py
It makes sense to make the TaggableObject a child of the ConfigObject,since in this case we can derive the Instance, Node and Cluster objectsonly from the TaggableObject and have a cleaner hierarchy.
