NetBSD upgrade from binary sets

After performing a source-way upgrade of my NetBSD system, I decided to try out a different approach using the binary sets.

I got all the sets I needed from a handy mirror, then I performed the following steps:

$ tar zcvf etc-backup.tar.gz /etc
$ cp /netbsd /netbsd.old

$ tar zxvpf kern-GENERIC.tgz -C /
$ tar zxvpf base.tgz -C /
$ tar zxvpf comp.tgz -C /
$ tar zxvpf man.tgz -C /
$ tar zxvpf text.tgz -C /
$ tar zxvpf games.tgz -C /

$ mkdir /tmp/tmproot
$ tar zxvpf etc.tgz -C /tmp/tmproot
$ etcupdate -s /tmp/tmproot/etc

After all the modifications needed to the configuration files were done, I just rebooted the system.
