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

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