Is it possible to get mkfs.ubifs to create an image without specifying the
max-leb-count ? I.e. just to create an image that is as big as it has to
be. Admittedly, one would have to figure out the size of the resulting
volume afterwards, to provide an allocation size for ubimkvol or ubinize,
so perhaps it would help much.

Thanks for the patch, I'll try to test it.
