That's hard for me to try as I'm using single reiser4 partition for all my  
data, after pushing my reset button several times I'm quite sure that my  
files are safe (if I won't hit any crazy bug ;) ).
But maybe You are right, it's slowly getting full and I did rebuild entire  
system few times. When I will have some free space for backup I'll  
reformat my disk.
