base-config equivalent to Etch?

[Ken Heard <ken@heard.name>]

Sarge has a command base-config which -- besides running as part of the 
installation process -- is also available to change or correct such 
things as the time zone, passwords, etc.  This command does not seem to 
exist as such in Etch.  Is there an equivalent in Etch?
