i only became aware that i was running mysql proper upon seeing 
the upgrade to 9.7, at which point i recalled mariadb was at 11, 
and was prompted to look into it. i planned to upgrade to 9.7 
and then convert to mariadb. i will now likely convert to 
mariadb without the upgrade to 9.7.

it was *not* my understanding that apt handled everything; i was 
under the impression that authentication had to be reproduced 
manually in the new mariadb, for instance. is this inaccurate?
