I have create a "live usb" system.
Uncompress it, use 'dd' to write it to a flash drive(256MB+ size), use /dev/sdX not /dev/sdX1.
(winimage can be used for windows.)
BE CAUTION, the data on it will lost.
Then use it to boot a computer.
You will see three menus:
"2013-03-19-3.8.3-x86_64 [ Copy to Ram ]"
This mode will load squash image to memory, the boot device can be removed after boot.
"2013-03-19-3.8.3-x86_64 [ Copy to Ram ] [ Local Overlay ]"
This mode will write back changed data to boot device, for now this feature must be used combine with [ Copy to Ram ].
Note: the written back datas will be seperate for different computers.
User name is "root", no password.
After login with root, you can run wayland by execute "weston_init", it's very very simple.
I'm not good at English, you can get more informations by reading /usr/share/mkinitramfs/init.sh
Good luck, Have fun.
