Re: /boot on ext2, 3 or 4?

Sorry, are you saying that it is possible to have the whole system
encrypted using lvm-luks or just lvm?

If it is just a test go ahead without /boot partition and whatever else you 
like to try. For a production system besides considering "whatever works" I 
would also consider how much effort and time I would have to invest if 
something goes wrong. How fast can I have the system back online and in a 
usable state. That may totally change the picture.
Murphy's law: If you provide for two different ways in which something may 
fail it will fail in a third and totally unforseen way.

Kind regards
