I've thought a bit about this in the past, and it might be doable in the future or via some kind of filesystem management package, if someone were to come up with one, but it isn't something that would be recommended (at least not yet) or supported. > I don't know a tonne about the innards of pfsense and I've never > played with the nanoBSD version.

You'd also have to alter the packages (or create appropriate symlinks if they can be followed by the application) to point those directories or files at the new storage location. Some packages might have built-in path settings and you'd just need to change the paths and hit save. Otherwise, you may need to alter the code for the package. As with most things, if you want to experiment, it's up to you, but do so with caution (and plenty of backups) and remember that you'll be out on a limb without a net to catch you if something breaks.
