Upgrade install fails when soft-links are used

If a softlink is setup at this below location when an install is done, but then an upgrade is done later, the soft-link is lost causing the upgrade install to fail.

soft-link location:
/usr/local/mariadb

So need to determine when the softlink is lost and try to prevent...

upgrade:

rpm -e ...
rpm -ivh ....

OR

rpm -Uvh ...
