Now you've made me aware of this I've deleted /var/log/wtmp. I doubt it
was using as much storage as you suggest but if I'd really been thinking
I'd have done a df before and after - maybe someone else will.
There's no need to link it to anything. If the file isn't there, then
logging is turned off - at least that's what should happen.
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.
