It actually turned out to be something a lot simpler. Unlike Linux, 
u-boot only allows one active ubi partition. However, because it uses 
the code from Linux, when trying to access a file system you still need 
to specify which ubi partition it's on, which was neither intuitive nor 
obvious until I dug through the code.

When I specified "ubifsmount ubi0:recovery", it worked perfectly.

Thanks?
