SYNOPSIS
xt-create-config [options]
Filename Options:
--output Specify the output directory to use.
--extension Specify the file extension to use.

All other options from xen-create-image, such as the new IP address(es)
to give to the new instance, will be passed as environmental variables.
ABOUT
This script is invoked by xen-create-image after it has created and
customised a new Xen guest. It is responsible for creating the
configuration file which Xen will use to start the instance.
The configuration file will be created in the directory /etc/xen using
a template file to determine how the configuration file should be
created.
By default the script will use /etc/xen-tools/xm.tmpl as its input.
INVOCATION
This script will be invoked by the xen-create-image script, rather than
directly.
This is because it will expect to receive the values to insert into the
output template in as environmental variables.
You could execute it manually via a long command line, but that is
error-prone and probably not useful:
hostname=foo.my.flat ip=192.168.1.2 ... xm-create-xen-config \
--output=/etc/xen --template=/etc/xen-tools/xm.tmpl
ARGUMENT PASSING
This script will be invoked with a full copy of the arguments from
xen-create-image in its environment, along with several command line
arguments.
This has several implications for customization. If you wish to
setup a new variable in the output template such as "foo=bar" you
could update the script to include "${foo}", then invoke
xen-create-image with this environmental variable set.
$ foo=bar xen-create-image --hostname=test.my.flat ...
The environment will be duplicated/inheritted by this script when
it is executed, and your variable will be included in the output file.
For details on the template file syntax please see the documentation
for the "Text::Template" perl module. (If you have the perldoc
package installed you can read this with "perldoc Text::Template".)
