If you just need a working server somewhere, then depend on the
appropriate server-core package instead. That drops in the binaries
without any configuration (and you'll need to arrange the configuration
and daemon startup yourself).

OK.

If you want a running server available, then I suppose you must
Pre-Depend on the server package.

I don't believe we've planned or been asked to provide this.

I believe you can just install mariadb-server manually and your system
will switch. However note that you cannot go the other way
automatically, so take a backup first.

If you have any customised configuration for MySQL in
/etc/mysql/mysql.cnf.d, you'll need to
translate this in /etc/mysql to MariaDB (/etc/mysql/mariadb.cnf.d?) as
well.
