thanks

I feel that this is too "dangerous" an option to allow 
without requiring the user to jump through hoops to 
configure it themselves.

There is no way this can be safe, and thus no way for it
to make sense except for test setups where you don't really
care if the encryption is severly weakened. 

For such test setups, it is IMO easy enough to install 
with encrypted swap or without swap at all and just change
the swap setup afterwards.

I'm happy to discuss arguments why it does make sense and
why we should introduce the option, but for now I just 
don't see them; hence tagging the bug +wontfix.
