Can you define UBI in each and every file you create?  This is a
completely unique acronym and I'm sure a bunch of people will be going
"wtf" when they read this, I know I was.

Neat stuff!  Too bad you don't have a more descriptive name for it,
UBI just doesn't seem to have any connection to LVM for Flash plus
