[Kimchi-devel] [PATCH 1/4] Upgrade to Kimchi 2.0: Save previous objectstore file.

[pvital at linux.vnet.ibm.com]

From: Paulo Vital <pvital at linux.vnet.ibm.com>

With the new structure of Wok and Kimchi, the objectstore file is deleted
when performing a upgrade from Kimchi 1.5.1 (or previous versions) to the
new Wok and Kimchi 2.0 RPM's.

This patch checks the current version of Kimchi, and if <= 1.5.1 it saves
a copy of the current objectstore file in the beggining of Kimchi 2.0
installation and restore this file in the end of the process.
