I wish that a response was not required before the persistant image will load on boot-up. I can understand that there's a potential security issue-but if a boot parameter specifically requests that the image be loaded it seems redundant and unnecessary to require more input again.
This might seem trivial bit it prevents me from using the persistant image feature for the system I'm trying to put together for my aging father. I want it to be a system he (or others) can't mess up; and I don't want him to have to do anything but power-up the computer to use it; essentially an internet/email appliance.
