hello,

I think that cache is your fossil filesystem, so, that 11%
are the files you can see in normal operation.

if i not missed all of that, venti "generates" your cache
(fossil) in which you can work like normal fs, and when
finish your work , the snapshot will write it to venti fs.

so you never will see an empty cache unless that fossil
does not contain your plan9 system disk.

you can create a fossil for the system and other fossil
for other purposes. That will allow you to empty that
fossil completly. I am not sure if you can dump two fossils
to one venti, but i suppose yes.
