Others mentioned "rsync" or "cp" (used recursively) might pick up these directories. These are good reasons, especially if you've got a few hundred snapshots, which would not be uncommon when using ZFS on a host that's doing disk-based backups. Other gotchas would be some of the periodic scripts - you don't want locate.updatedb traversing all that, or the setuid checks. Also I know I'm prone to sometimes doing a brute-force "find" which can also dip into those hundreds of snapshot dirs. In general, I think having the directories hidden is a good default. Wouldn't be opposed to having the "pwd" issue fixed though...
