In the example init script we'll execute an optional defaults file to

This patch adds a couple of both externally and internally reported
issues:
  - missing SGML tags (Issue 54), report and patch by superdupont
  - wrong variable used in the init.d script, report and patch by
    Karsten Keil <karsten-keil@t-online.de>
  - man page for gnt-instance reinstall needs clarification (Issue 56)
  - gnt-instance man page missing --disks documentation for
    replace-disks
  - gnt-node modify help output is unclear about the -C/-D/-O input
    format, and the man page doesn't document this command at all
  - “gnt-node modify -C yes” for offline or drained nodes had wrong
    error message
  - “gnt-instance reinstall --select-os” has wrong prompt, we only
    accept a number for the OS and not the template name

This patch adds the newly-introduced node flags to the design document,
as they currently are missing from there.

The patch also reduces the TOC depth to 3, as it was too big.

“copyfile” takes a file argument, so we enable file-completion for it.

This patch export the cluster and node tags to the cluster verify hook
scripts. The tags are exported as a space-separated list, which allows
easy parsing from the shell (e.g. “for tag in $GANETI_CLUSTER_TAGS; do
...”) and therefore requires the previous “Don't allow spaces in tag
names” patch.

The patch also fixes a minor line length style problem.

This patch changes the RAPI document, and the RAPI resources
autogenerated-documentation to restructured text. This meant changing
the autogen tool.

The new fragment can be included via RST directives, and doesn't need
passing through replace-sed-vars. This was also the last sgml document
in doc/, so we remove old makefile rules about it.

This switches back to the hardcoding of the version number, as we don't
yet have a wrapper for rst files that passes them through
replace-sed-vars.

This is a not-complete bash completion file for ganeti commands (gnt-*)
and the burnin tool. It is based on previous work by Minghua Ye
<yeminghua@google.com> for Ganeti 1.1, which wasn't used because the
lack of ssconf keys (which allow easy inspection by the shell of the
existing nodes and instances) made it too slow.

The file works as expected, however I realized that our custom (like
comma-separated, or a=b:c,e:f) options are not very nice for
auto-completion. There are a few FIXMEs in the source for that.

The file is not installed at make install time, but it should be put in
the correct place by packages.

This is a no-contents change, this doc will need update to conform to

The RST format holds a little bit less information, as all the <file

This patch fixes the gnt-instance batch-create command, and in doing so
also slightly changes two other functions:
  - we change utils.ParseUnit so that it accepts integer values also
    (both ParseUnit(5) and ParseUnit("5") return the same value)
  - a bridge 'None' in LUCreateInstance will be converted to the default
    bridge; currently only missing bridges will be accepted to mean the
    default one

The main changes to batcher were the change to variable number of disks
and NICs.

The patch also adds a batcher-instances.json example file copied from
the 1.2 branch and properly modified.

This patch changes the iallocator framework to work with and properly
export to plugins offline nodes. It does this by only exporting the
static configuration data for those nodes, and not attempting to parse
the runtime data.

The patch also fixes bugs in iallocator related to the RpcResult
conversion, changes the should_run to admin_up attribute name (as per
the internals change), and adds “-I” as a short option for
“--iallocator” in gnt-instance, gnt-backup and burnin.

Internally in ganeti we already have renamed the instance, so it's
better to pass the new name in INSTANCE_NAME and the old one in

The idea is that if the OSes will support multiple version (e.g. both

2.0, but then the script needs to be told nicely what version Ganeti is
using.
