F10 Live CD possible bug

[Nathanael Noblet]

Hello,
   I downloaded the live cd of F10 beta. Booted and added the live_ram  
option to the boot params. After copying the image to RAM I get the  
following error on two machines, (Apple Mac Book, and Acer 3680).

Done copying live image to RAM.
eject: did not find a device /dev/root in /sys/block
Bug in initramfs /init detected. Dropping to a shell. Good luck!

sbin/real-init: line 7: plymouth: command not found

I know I used that param for F9. Is it depreciated or is this a bug  
needing filling?
