editfiles and iteration

[Bobby Billingsley]

After a browse through the mail archives and the web docs I still can't
figure out how to go about this little puzzle.

I've got a (perl)script generating a bunch of groups/classes ang control
variables, amongs these is a list of NTP servers (which aren't the same for all
hosts).

What I'd like to be able to do is have some kind of editfiles stanza add/modify
lines in /etc/ntp.conf based on the list of IPnos. defined in the NTPservers
variable.

Currently my script is generating cfagent.conf entries similar to the following
example:

    # -- cfagent.conf 
    groups:
        HostGroupA = ( hostA hostB hostC )
        HostGroupB = ( hostD hostE hostF )

    control:
        HostGroupA::
                NTPservers = ( 1.2.3.4 2.3.4.5 3.4.5.6 )
        HostGroupB::
                NTPservers = ( 6.5.4.3 5.4.3.2 4.3.2.1 )


...what I'd like to do is add/modify entries in /etc/ntp.conf similar to these:

    # -- HostGroupA /etc/ntp.conf
    server 1.2.3.4 minpoll 4 maxpoll 7
    server 2.3.4.5 minpoll 4 maxpoll 7
    server 3.4.5.6 minpoll 4 maxpoll 7

and

    # -- HostGroupB /etc/ntp.conf
    server 6.5.4.3 minpoll 4 maxpoll 7
    server 5.4.3.2 minpoll 4 maxpoll 7
    server 4.3.2.1 minpoll 4 maxpoll 7

based on the NTPservers variable.

I'm sure that this isn't the only situation where one would like to do
something similar.

Any suggestions?
