rpm install removes link to actual install location

Version 1.0.8 for Column Store was installed on a fresh system. For data balancing reasons all of /usr/local/mariadb was moved to a separate drive and a soft link made to the location.

Following update instructions prior to installing version 1.0.9 rpm was used to uninstall 1.0.8 which in the process created the file Columnstore.xml.rpmsave and others in the appropriate linked to directory.

1.0.9 was installed and /usr/local/mariadb/columnstore/bin/postConfigure -u was run. It indicated Old Config File not found '/usr/local/mariadb/columnstore/etc/Columnstore.xml.rpmsave', exiting

The root of the problem turned out to be that as part of the installation, the link was deleted and a new /usr/local/mariadb directory was created and software installed there. This is why the rpmsave file could not be found.

This is serious as both configuration and existing data are in the old linked-to location. It is unknown how much work is involved in manually copying updated files and re-establishing soft links, and whether there are errors in this process
