Linux sistemi açılış sırasında ekrana açılış notlarını göndermektedir. Bu loglar çekirdek log tamponuna yazılmaktadır. Çekirdek log tamponunu listelemek için

        dmesg

komutu kullanılır. Çok önemli olan bu logların kaybını önlemek için açılış scripti bu logları /var/log/dmesg dosyasına yazmaktadır.
