The first time it's mounted, all the blocks need to be erased and 
formatted correctly. That's done in the context of kupdated. The Use% field 
is high because the blocks are being taken out of the list of available 
blocks - we should probably fix that.

Probably not. If you want rtime first you might as well just omit zlib 
completely. And yes, rtime will be faster.
