How effectiate login.conf changes in console? ("ksh -l" does not)

Hi,

After having changed /etc/login.conf I'd like to effectuate the
changes directly in the console, without doing a logout-relogin
cycle.

Running "ksh -l" does *not* effectuate login.conf changes but only
re-runs the profile script [1].

Running "login" asks for username and password which seems less
efficient than possible.

Is there any way to do this?
