DESCRIPTION="Move your database to a new location, like a USB drive"
INFO="Note that non Unix filesystems such as NTFS are not supported
because they do not provide a compatible user/permissions system
You need to use a USB drive that is permanently on and is responsive
or the database will fail.
** If it ever fails with a white page, move the database back to the SD **"
