	Ah.  This is one that I personally would solve with Perl (or 
rather, the perl templating solution that I use), and then run that using 
cfengine's "shellcommands".  AFAIK, cfengine editfiles doesn't have a 
facility for putting a line into a variable (or rather, only into the 
currentline variable, which acts like Perl's $_ variable), and neither do 
I know of any way to write to a non-current file using editfiles.  Hmm. 
Mark, we might want to consider solving these problems when we redesign 
editfiles in the future.  I'll try and remember to add a link to this 
thread to the wiki once these posts appear in the archive.

	If you really wanted to solve it with cfengine, the only way I can 
think of is:
1.      Use a "copy" stanza to copy the base file to a temp file
2.      Use editfiles to transform the temp file into exactly what you
        want in the config file
3.      Use a shellcommands "mv" to copy the new config file over the old
        one.

        There may be other solutions, but I'm unaware of them.

        :)
