Currently the version.py file hardcodes some basic info for
the NOVA_PRODUCT, NOVA_VENDOR and NOVA_PACKAGE constants. It
is desirable that OS distro vendors can override/extend this
data in packages they ship. Cloud providers may also desire
to do the same. This allows Nova to optionally load this
data from a /etc/nova/release file. That file should contain
the data in a trivial "ini" format. For example:
[Nova]
vendor = Fedora Project
package = 1.fc18
Note that vendor sare not required to override all strings.
In this example, the 'product' field is not set, leaving
it on the default 'OpenStack Nova' value.
