Yes, correct.

The reason we were forced to introduce mysql-fixperms is one
shortcoming in MySQL's permission model.

When you grant DROP on DATABASE.* to someone, then that rule also
implicitly gives them the privilege to DROP not only all tables, but
also the database itself.

And we can't allow database drop, because it would delete files from
our custom location, and then the re-run of "CREATE DATABASE" would
create it in the incorrect location on the disk.

The only way to have mysql grant drop on tables but not on the database
is to name tables individually. So what mysql-fixperms does is look 
into your databases, find tables, and explicitly grant you drop on 

Note that you only need to run it when you add new tables for the 
first time... If you drop and re-create tables at some point, the
permissions still stay there so no need for another fixperms.
