# MariaDB 10.2.31 - Stable (GA) release (from 2017-xx-xx)

# By default the mysql.sock socket file is located in /tmp
# If you want it accessible as another path, create a symlink as root:
#  su -c "ln -s /tmp/mysql.sock /var/run/mysql.sock"
# or tell CMake where it should go, then that will be the new default:

# /usr/local/mysql/data or (/var/lib/mysql) at least temporarily copy
# them to another path until the upgrade is done and confirmed OK

# Because it is a drop-in replacement, remove both the mysql and mariadb
# Slackware packages
