After an installation of grml 1.0-1 I followed the instructions of the man page 
of grml2hd and made a crypted swap and a crypted home partition. Everything 
seems to work fine so far but when I get the instruction while booting to enter 
my passwort to unlock my home partition and I enter a wrong password the kernel 
gets panic. I even don't get the chance to enter it twice.

The man page also says that you have to edit /etc/runlevel.conf to adapt it but 
that's wrong, everything was already fine there.
