UBI/ubifs problem

[Ricard Wanderlof]

Yesterday I reported a problem I had when flashing a ubifs volume.

I think I've figured this out part way. I've been specifying a 
--max-leb-count of 1000 to mkfs.ubifs, thinking that it basically just 
sets a maximum size for the resulting file system. But it seems that it 
also sets some sort of bounds for how much space it expects to take up in 
the volume. If I reduce the --max-leb-count to the size of the target 
volume, I get no errors and the file system mounts fine.

That being so, I think the resulting error message is odd, which indicates 
there is a bug somewhere, probably in mkfs.ubifs ?
