we found out the hard way that new versions of mariadb in fedora 25 upstream (not the one in the DVD), and in the latest fedora 26 DVD, have an issue where the initial password setting in hda-install using mysqladmin breaks.

the work-around is to downgrade mariadb before hda-install (or after it was run but failed) with this command (though I'm not 100% sure of it, it may require adding mariadb-common to the downgrade command):

dnf downgrade --allowerase mariadb

the error as it appears to the user in the terminal looks like this and installation does not finish due to it:

Initializing MySQL
...
Activating your HDA's settings
ERROR 1045 (28000): Access denied for user 'amahihda'@'localhost' (using password: YES)

in the hda-install-X.log file, it looks like this:

...

You cannot use 'password' command as mysqld runs
with grant tables disabled (was started with --skip-grant-tables).
