Pretend I've got an MTD partition attached as a UBI device.

That UBI device contains a couple differen UBI volumes.

In one of those volumes is a UBIFS filesystem that has a bunch of
files in it.

I've done some googling, but all of the answers are "use
ubiformat". That will wipe the whole device. I just want to
re-initialize one ubifs filesytem in one volume -- not the whole
ubi device.

How do I wipe that filesystem (set it back to empty).  Do I need to
create an empty ubifs "image" file using mkfs.ubifs and then use
ubiupdatevol to write that image to the volume?

Isn't there a simpler way?
