Huh?  How so for programs?  Using the gettytab `if' seems fairly
simple and convenient for programs.  I can maybe accept it being
difficult for scripts.

Too bad none of the systems I've looked at implements this in
the same way.

How various modern Unix-like operating systems use /etc/issue.
  OS            Displays /etc/issue
  ------------- -----------------------
  HP-UX 11      getty
  IRIX 6.5      login or getty
  Linux         getty
  OpenBSD 3.3   telnetd iff no /etc/issue.net
  Solaris 8     ttymon
  Tru64         getty or telnetd
  UNICOS 10     login

From my searching these appear to be the only Unix-like operating
systems that specifically use or look for /etc/issue.net.
  OS            Displays /etc/issue.net
  ------------- -----------------------
  Tru64         telnetd
  Linux         telnetd (Note: treated as *interpreted* text)
  OpenBSD 3.3   telnetd

These systems telnet daemons could use /etc/{issue,issue.net} with
proper configuration.
  OS            Configure to display /etc/issue or /etc/issue.net 
  ------------- -------------------------------------------------
  Solaris 8     set BANNER appropriately in /etc/default/telnetd
  HP-UX 11      set in inetd.conf with telnetd -b [banner-file]
  FreeBSD 5     set `if' for default entry in /etc/gettytab
  NetBSD 1.6    set `if' for default entry in /etc/gettytab

All this information was determined from publicly available man
pages and source code.  So I might have missed something...
