Interesting... > It only seems to clear '/var/tmp' currently. I don't know why we have > missed the wtmp file... Interestingly an older firmware image (W48-someting) did not write a wtmp! Just checked on another not yet updated device.

I guess this would not work since wtmp is written to with every close of the 770 case (for whatever reason). so it will be modified too often - at least in my case since I open the 770 at least once to 10 times a day. > BR; Kimmo Cheers nils > On Wed, 2006-04-12 at 17:34, ext Nils Faerber wrote: >> Hi! >> I thought I should let you know... >> >> I am not sure if I really found any cure to anything but after the >> latest discussions about the size of wtmp I checked mine on the 770 and >> found a more than 200MB file! >> >> After gzip'ping it it shrank to just 5MB because it contains almost only >> 0s.
