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.

Since on dual-homed clusters one always needs to add '-s' to the
gnt-node add command, make this appear in the output of 'gnt-node' (when

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.

The install manual was missing python-pyparsing and python-simplejson from the
apt-get install list. Adding them.

Thanks to Henning Sprang for spotting this issue.

Right now an assembly error produces an exception but not a log message. This
is bad because the exception suggests looking at the log, but the log itself
has a lot of errors which are not really a problem and only some which really
is. In order to make it clear where in the log the problem occurred we log a
message too, before raising the exception.

We want to prevent sending too many 'None' children to a device.
However, the test as it is today is wrong, as we want to test the
situation after adding a new child, and not before. This patch fixes
this by testing greater-or-equal instead of just greater.

The code assumes all lines have at least two elements which are
whitespace separated - i.e. it does not deal with empty lines or comment
lines with no spaces. This patch fixes this.

Also, the patch replaces the blank between IP and the canonical name
with a tab (restoring previous behaviour).

This is a critical file. Breaking it would be very bad. Thus, if the system
crashes before the data is synched to the disk, it should have the complete
file afterwards.
