First off I would assume it would mount the filesystem writable with
very little free space available. Here I am assuming the mininum LEB
count mkfs.ubifs calculates is legit and that the same goes for the
journal and log sizes.

Also, my current understanding is that the LEB calculation is based on
uncompressed size. If ubi uses compression runtime then the amount of
LEBs actually used is smaller, no?

I'll have to do some tests on the topic and see how it behaves. I'll get
back to you.
