rootになってみよう。とりあえずsudoしてみると、すんなりrootになれた。
pi@raspberrypi:~ $ sudo -s root@raspberrypi:/home/pi#
初期はどうなってるか確認しておこう。とりあえず割と普通。
root@raspberrypi:/home/pi# cd /root root@raspberrypi:~# pwd /root root@raspberrypi:~# ls -aFC ./ ../ .bashrc .profile
updateをかけてみたくなったのでやってみる。Debian系だからapt-getでできるはず。
まずはパッケージリスト自体の更新を行う。

この後、インストールされているパッケージのアップデートを行う。apt-get dist-upgradeを使うと依存関係も含めてパッケージをアップデートしてくれる。

電源OFFしてもバージョンアップできているか確認してみる。
電源OFFはshutdown -h nowでできる。電源ONはUSBケーブルを抜き差しする。
