Ah, sorry, should have been more explicit. In my case it is a field of
operating-system. So in your case try something like
(operating-system
...
(host-name "foo")
...
(kernel-arguments (cons* "console=ttyS0,115200n8"
%default-kernel-arguments))
...)
From there it should automatically propagate into all auto-generated boot menu
entries.
Hope it helps this time,
