セットアップは Fedora 19 のときとおなじ。
https://dl.fedoraproject.org/pub/fedora/linux/releases/20/Images/armhfp/
初期起動の際に、停止してしまったので、手動で再起動してから、初期セットアップ画面をすませる。
HDMI から VGA へ
SELinux や firewalld とめた後は出力を HDMI から VGA へ（fedora 20 イメージのREADMEに記載あり）
/boot/uEnv.txt を編集
■変更前
loglevel=5
root=/dev/mmcblk0p3 ro rootwait rootfstype=ext4
extraargs=console=ttyS0,115200 disp.screen0_output_mode=EDID:1280x720p60 hdmi.audio=EDID:0 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 sunxi_fb_mem_reserve=20 sunxi_no_mali_mem_reserve
■変更後
console=tty0
loglevel=5
root=/dev/mmcblk0p3 ro rootwait rootfstype=ext4
extraargs=console=ttyS0,115200 disp.screen0_output_type=4 disp.screen0_output_mode=1920x1080 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 sunxi_fb_mem_reserve=20 sunxi_no_mali_mem_reserve
これでVGAから画面が出る

The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy
The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
/ の拡張
「/」のあまりが非常に少ないそのため、以下を実施
- 一度「/」データを別のLinuxマシンに退避
- 「/」の部分をパーティション切りなおし（fdisk）
- ファイルシステム再構築、データの戻し
- fstab は uuid 指定になっているのでデバイス指定に変更（例：/dev/mmcblk0p3 / ext4 defaults,noatime 0 0）
- cubieboard2 へ SD 挿入し起動
fstab を変更せずに起動すると、uuid 相違のせいで read only でマウントされ何もできない
uuid 指定でもいい、以下のようにわかる
[tk@cubie2 ~]$ cd /dev/disk/by-uuid/
[tk@cubie2 by-uuid]$ ls
