[chef] is there a smart way to tweak configurations file in chef? (or puppet, cfengine, or otherwise?)

[Thomas Hartman <thomashartman1@googlemail.com>]

I have this scenario where I have a my.cnf ini file, and I want to
make sure it has a certain value in a certain section. (Can't just
append to the end of the file.)

I solved this using the perl file, attached. Obviously this isn't a
perfect solution though. If the value is already set, but set wrong,
it won't work.

The right way to do this would be to parse the ini file and do something 
smart.

I am just wondering if this kind of tweak is a solved problem, in
chef, puppet, cfengine, or anywhere else.

Thanks in advance for any advice!
