Hi Everyone,
I have a suggestion for CFengine. It would be nice to be able to have a
plain text config file with variables, which could be read by a client
on a host by host, and/or class by class basis.
The data would be read in by CFEngine (probably set in cfagent.conf) and
would be available to all subsequent cf files being processed.
I did something a while ago because I wanted to read the same data in
Perl as PHP for a project I have been dabbling with.
Anyway, an example config plus working Perl code is below. It would save
me having to use complicated bash code to extract data from a plain text
file. I have a config file per host which means I can define each boxes
purpose outside of CFEngine, which makes it easier to maintain.
Cheers,
Marco

PERL CODE TO EXTRACT FROM CONFIG AND DUMP INTO ARRAY

close CONFIG;
