Checking the correctness of the NEWS file syntax is an important part of the

Update the upgrade design document according to the outcome
of the design discussion at GanetiCon 2013. There are two
changes in the design.

* As revision upgrades are binary compatible at all levels,
  one can accept a rough upgrade, just replacing the binaries.
  Therefore, it will become a configure option whether version
  includes revision and suffix, or not.

* The install/uninstall scripts are replaced in favor of another
  level of indirection. In this way, at run time, only two symlinks
  in ${sysconfdir}/ganeti, will be changed, whereas links under
  ${PREFIX}/bin, ${PREFIX}/sbin, and similar, are not touched by
  ganeti itself.

* The layout for the ganeti python libraries, which do not provide
  stable interface, are changed to be used as private modules.

LD_* constants are basically like DT_* constants, except
for that both file and shared file were mapped to file.
In order to not having to maintain three slightly different
sets of disk-related constants (DT, LD and ST), we merge
DT and LD here. This patch does the renaming of the
various constants and then fixes the handling of shared

This design doc adds details about how the autoconfiguration of
openvswitch should work in the cluster <-> node group <-> node
hierarchy. Parameters that are needed for succesful configration
are idenfied and inheritance of parameters is defined.

Also, some rephrasing of the definition in the first part of the
document. After looking into gnt-network, in my opinion it is not the
right place to put the switch management into, since it has more to
do with links and nics than with network names and addresses.
