ここを参考にして、
ubuntu-saucy-13.10-armhf-3.8.13-bone30.img.xz
をSDに焼く。
i$ sudo dd bs=1m if=/Users/toshifumi/BeagleBoneBlack/ubuntu-saucy-13.10-armhf-3.8.13-bone30.img of=/dev/rdisk3
5分で焼けた。
BBBにいれてBootボタンを押しながら起動。
シリアルコンソールでログインOK。

etherもつながっています。
uEnv.txtを編集して再起動。Bootボタンを押さずにUbuntuが立ち上がりました。
mmcpart=2
bootfile=zImage <---- 追加
optargs=fixrtc
uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc

mmcboot=echo Booting from mmc ...; run mmcargs; bootz ${kloadaddr} - ${fdtaddr} <---- 追加
そして、2GBから4GBに拡張。
作業は参考ページと同じ。

今はまだサイズが1.8GBになってますので、fdiskで拡張します

ここまで来たら、先のBootボタンを押しながらリブートします
ubuntu@ubuntu-armhf:~$ sudo reboot
起動したら再び
sshで接続してログイン後、resizeコマンドを叩きます
