Let us make innodb_buffer_pool_filename a read-only variable so that a malicious user cannot cause an important file to be deleted on InnoDB shutdown. An attempt to delete a directory will fail because it is not a regular file, but what if the variable pointed to (say) ibdata1, ib_logfile0 or some *.ibd file? It does not seem to make much sense for this parameter to be configurable in the first place, but we will not change that in order to avoid breaking compatibility.
