Re: simply, yet elusive import: question

[Christian Pearce]

Kelly you are prob right, but to answer Nathan's original question, I
would do the following.

Ditch main.cf.  What is the point?  Just make main.cf your cfagent.conf.
Don't add to the confusion of imports.  Next create a second file that
actually does your service restarts.

Here is my example:

bash-2.05b$ tail *
==> cf.config <==
editfiles:

    { /var/tmp/somefile
        AppendIfNoSuchLine "line"
        DefineClasses "RestartService"
    }

==> cf.services <==
shellcommands:

    RestartService::
        '/usr/bin/echo "I am restarting the service"'

==> cfagent.conf <==
control:

    actionsequence = ( editfiles shellcommands )

import:
    cf.config
    cf.services
bash-2.05b$ touch /var/tmp/somefile
bash-2.05b$ /usr/sbin/cfagent  --inform -K   
cfengine:: Saving edit changes to file /var/tmp/somefile
cfengine:: Executing script /usr/bin/echo "I am restarting the
service"...(timeout=0,uid=-1,gid=-1)
cfengine::r/bin/echo "I a: I am restarting the service
cfengine:: Finished script /usr/bin/echo "I am restarting the service"
bash-2.05b$ /usr/sbin/cfagent  --inform -K 
bash-2.05b$

Notice the second time it doesn't output that it is doing something.
(And yes I ignore locks it make it work immediately)

Finally you can see the graph I attached.  Any files that are imported
after cf.config will have cf.config's variables and defined classes.

Oh one thing to note that editfile will not work unless the file exists.
So I touched it ahead of time.
