editfile question

[Sean Atkinson]

Hi,

Recently I've been getting to grips with cfengine, hoping to use it to
manage all the configuration details for large Linux desktop
deployments.  As an example to understand its use, I want to apply the
following diff to the X server's configuration file to add support for
remote access with VNC:

--- XF86Config-4.orig   2005-02-25 19:35:01.154611824 +0100

Integrated Graphics]"
        Monitor         "Generic Monitor"

However following the reference documentation I can't figure out how to
achieve this with the available editfile options.  It would have to
consist of a search, test for the new line's existence, and conditional
insertion as necessary.

Does anybody have any advice on how this might be done please, or should
I be looking for another solution?

Cheers,

Sean.
