Author: dab Date: Mon Sep 25 20:04:14 2017 New Revision: 323992 URL: https://svnweb.freebsd.org/changeset/base/323992 Log: MFC r323252: Add a new getty/gettytab capability to generate an initial message dynamically. This modification adds a new gettytab(5) option (iM) to specify a program to run that will generate the initial (banner) message that is displayed before the login prompt. Such a capability is useful when dynamic information is needed in the banner message that cannot be supplied by the set of % substitution sequences available in the "im" option.
