FFS is woefully inadequate at handling databases, due to the block indirection, but e.g. Oracle will allow you to run directly on top of a device. As to the cylinder group count, couldn't we, rather than changing the default, have a new flag to newfs which takes it to the maximum possible, and preferrably another one to try to keep the number of cylinder groups sane by pushing the block size etc up automatically?
