Wrong, this just deletes everything that is stored prior to this. And 
no, what you assume is wrong. Of course the log files should be 
erasable, and if user deletes the log file, then the system should just 
start making a new one.

Creating the log file if it's not there is the right thing. and turning 
off the logging should be done via config file.

And, my wtmp file was 96.5MB, will be posting if the linking helped 
anything. And yes, i have too found that the system is more sluggish 
than in the beginning of use. Even enabling swap-space on the mmc dont 
have any help anymore.
