    echo MariaDB will now ask you *twice* for its root user\'s password.
    echo
    echo If this is a fresh MariaDB install and you do not have a root password,
    echo leave the \"Enter password:\" prompt empty and just press \'Enter\' to continue.
    echo
    echo After this setup is finished, you should run \'mysql_secure_installation\'

    # Create ZoneMinder's database & user
    # NOTE: This should probably take into account the possibility of the database already being in place from a previous ZoneMinder install, and will need some way of upgrading it instead of trying to recreate it (which will possibly cause some issues). Until then, please do not upgrade an already existing database, rather, make a backup of the current database, delete the original and let this script create a new one from scratch. Or, if you so wish, you can let this script fail and then upgrade your database by hand.
    # NOTE 2: I removed the post_install call that used to reside inside post_upgrade (nothing here should need to be run when upgrading, and apparently zmupdate.pl takes care of all the required internal legwork) so this step shouldn't cause any issues anymore because it simply won't run on subsequent upgrades.
