Snapshots are always enabled, and can be placed anywhere. .snap is used by background fsck, and newfs creates that directory so that it's guaranteed to exist when fsck needs it. You can use create it manually if you want, or create another directory to put your snapshots in. -- Dan Nelson dnelson@allantgroup.com
