Running openELEC completely from usb

Running openELEC completely from usb

on linux : 
1. run ./create_sdcard on usb
2. run ./create_sdcard on sdcard
3. plugin usb and sdcard and bootup pie
4. ssh into device:
# df -h 
[ make a note of where the usb is mounted , usually

/dev/sda1 is /var/media/System [ rootfs ]
/dev/sda2 is /var/media/Storage [ user filesystem ]


# mount /flash -o remount,rw
# nano /flash/cmdline.txt

edit it like this:

boot=/dev/sda1 disk=/dev/sda2 ssh quiet


5. reboot , and it shall boot from usb
6. df -h looks like this:

-------- as opposed to autostart.sh modification we usually do :

/dev/sda1 on /var/media/STORAGE type ext4 (rw,nosuid,nodev,noexec,noatime,data=ordered)
/dev/sda1 on /storage type ext4 (rw,relatime,data=ordered)
