Hi Noah,
thank you for answer.

My problem is that, in the case of keystore update, I have to create a copy of the keystore, add or substitute required certs (only possible through bash commands) and then compare the modified keystore with the original in order to understand if I really added new certificates. Only in that case I will replace the original one. So I think I have to execute "bash" resources anyway.

One other possible case is the following... In a recipe I define my LWRP like this:

  wso2platform_greg wso_progr  do

    ...

    private_key wso_key
    public_cert wso_cert
    cacerts wso_cacerts
    action :install
    notifies :initialize, "wso2platform_greg[#{wso_progr}]", :delayed
  end

In this case, if :install action changes the configuration of my resource I have to re-initialize the server.

The :initialize action only restarts the server with some particular command line parameters, but I've to make this operation through a "bash" resource.

This seems to start an infinite loop as the "bash" resource cause my resource to be marked as changed and this starts notification again.

I would like the "bash" resource to cause a notification only when it really modify my wso2platform_greg resource, if possible.

Thank you

Use not_if/only_if to make their activation idempotent.
