It would be helpful if pcs had the option to edit and update the cluster configuration in one go, for example something like "pcs config edit"
This should open the current cluster configuration in text format in the users text editor (defined via the $EDITOR env. var.) and after the user saves the changed version pcs should check the updated config for any errors and if it is correct it should automatically be pushed out to all cluster nodes.
[root@ask-02 ~]# EDITOR=vim pcs -f temp.xml cluster edit
Pops open vim with the cib from temp.xml (or creates a new one if temp.xml doesn't exist).
