Managing Daemons in Heterogeneous Linux Environment From Puppet

We have a lot of box mixed with heterogeneous linux environment. So managing a daemons is a bit struggling. So worte my own manifest to over come this. I don’t know what other options there are, But this seems to kind of work for me. This can be scale upto N number of linux flavours, currently I have the manifest including only CentOS, OpenSuSE, Ubuntu.

Let me know if you have any trouble with it or any improvement is always welcome.

You can call this defination from any other module like this. I’m calling from my vsftp module.
