That's not needed, it should be sufficient to have them all in the boot 
runlevel:

No, it does not make sense. You don't even need an initrd.

As said above, it's not not needed. Maybe it's better to investigate wether 
there are any leftovers from baselayout 1 in the runlevels. This was at least 
the reason I got an unbootable system after switching to bl 2.

HTH...
