We want the name of the example OS to be nicer for packagers, so update
the install documentation accordingly.

Also, put in a notice about using the latest release OS version, so if
we forget to update this doc, we are not completely wrong.

This reverts commit 397, as the support in autoconf for docdir is
present since 2.59c, and this is too new for some distributions.

The /var/run directory can be a tmpfs mount, so even if we make it at
install time (or include it in the package) it can go away. Therefore,
test for its existence and create it in the startup script.

The docdir variable is defined by autoconf, so we don't need to define
it ourselves. This way, the target documentation directory can
be changed via ./configure instead of patching Makefile.am.

In truth, we should install the pdf and html files using the pdf and
html targets, since configure defines pdfdir=htmldir=docdir; but
installing them in docdir is good enough.

By default xen tries to save running virtual machines at system shutdown and
restore them at reboot. Make sure we suggest to disable this feature in the
installation manual.

This patch does:
  - add drbd8 information to the docs (the new disk template, examples,
    etc.)
  - fixes a section header to make it more clear
  - update the NEWS file by changing format (format taken by looking at
    /usr/sharea/doc/*/NEWS.gz) and adding more information on changes
    since beta1

Currently, an unreachable node (or one that return undetermined failure)
in the hooks pre-phase will abort the curren operation. This is not
good, as a down node could prevent many operation on the cluster.

This patch changes a RPC-level failure (and not a hook execution
failure) into a warning. It also modifies the related test cases.

This fixes issue 11.

This duplicates some code from the DRBDev class, but not very much, and
it will be expanded with the new functionality available for the 8.x
version. Currently the code is not accessible outside the module.

This patch introduces a dependency on the pyparsing module.

This patch adds a new option to the instance removal command
"--ignore-failures" that forces the removal of the instance from the
configuration even if the removal process encounters errors.

In order to be able to do this when the remote node(s) is(are) down, we
need to restrict the execution of the instance removal hook to the
master only. I think this is a reasonable trade-off (but I'm not sure).

I was getting into trouble with gnt-backup and discovered reading the
code of the debian-etch os image and the error logs that:
     1 - Debian os image shipped by ganeti depends on the availability
of dump and restore.

Based on that I had included in the section of "Installing the
Operating System support packages" the dependency of dump/restore and
the command to install dump/restore.
