If you're asking how both of those happen, it's because kernel messages are saved in an internal buffer, and can be dumped later. See the dmesg man page for information on how to dump them, and the /etc/rc script for how /var/run/dmesg.boot gets created. If you're asking why we do both, the second was presumably added to guarantee you could always recover the boot dmesg, no matter what else has happened on the system.

Why one printf statement can do that = > two=20 > works?
