home.img預設只有80GB，但是，司徒購買的Pro1 X是256GB，因此，找了一下網路資料，發現可以使用如下方式擴展到最大空間：

$ mkdir /tmp/test
$ sudo mount -o rw /dev/block/sda13 /tmp/test/
$ devel-su
# cd /tmp/test
# rm ./halium-rootfs/etc/sailfish-device-encryption-community/config.ini
# vim ./halium-rootfs/etc/sailfish-device-encryption-community/devices.ini
    size_mb=204800

# rm ./halium-rootfs/home.img
# exit
$ cd
$ sudo umount /tmp/test
$ sudo reboot

重新開機後
