Perhaps we could have mysql-server.postinst follow some heuristic to determine if the system has lower-than-will-work-by-default memory, and if so, then enable a (/etc/mysql/mysql.conf.d/lowmem.cnf -> /usr/share/mysql/lowmem.cnf) symlink or something. We could have a low priority debconf option to permit (no heuristic/always lowmem/never lowmem/use heuristic) overrides.
