There can be issues during database migrations when a column used as a foreign key is using a different collation between the parent and child table. Update the my.cnf template to set the server default collation to utf8_general_ci to ensure consistency between tables initially created with and those later altered to use the utf8 character set. This matches both the instruction from the OpenStack install guide[0], and MariaDB's default for the utf8 character set[1].
