Disallow copy session to RAM at first bootup

I received an email from a chap, who, I think, chose the boot menu option "Copy session to RAM & disable drives" at the very first bootup. The problem with this is that there is not yet a session to be copied to RAM. There has to be one normal bootup first.

I have put in a test in the initrd, that detects this situation and puts up a message then changes to a normal bootup.
