[chef] Re: Re: Re: Chef Recipe inserting a line before last line in fie

[Juanje Ojeda Croissier < >]

As I had a similar problem time ago, i did create a similar cookbook
(which is also at the community site and be installed from there):

https://github.com/juanje/cookbook-conf

There are some examples about how to use this LWRP. Maybe one of them
fit your needs.
I have one action that append a line just after specific line, but not
to prepend, but I could add this action easily if is needed.

It's something to be used just if is really no way to use a template,
it tries to be as much idempotence as it can.
