Regarding this file:

http://setup.hashfast.com/files/hashfast-20140224-0-multiarch.tar.gz

Since that has a RPI version on it, can I just SSH into my RPI, wget the file, and run it?  There's a warning about writing to a different SD card, but that's for the auto-upgrade image, which I don't need if I just run the upgrade from the above archive, right?
