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.

/usr/local/mariadb

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

upgrade:

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

OR

rpm -Uvh ...

the datax soft-link gets maintained..

thought is it update install docs to have user use binary package if they need to use /usr/local softlink

Investigation showed that the softlink at the base install level /usr/local/mariadb is being done by the rpm command when the erase is done. This is standard with all rpm package install.

So this means that it's invalid to do a softlink at base level and use the rpms to install.

So if the need is to continue to have the softlink at base install level /usr/local/mariadb, then you would need to change to use from using and installing rpm packages to using a binary package...
