I like to install multiple instances of Node-RED with a single user on Linux. For doing that, I used to get Node-RED source code from GitHub and then using Visual Studio I substituted all .node-red words inside its source code with .node-red2 or something else. Well, that used to work in the past but I tried doing the same and it doesn't work with version 2.2.2.
After running npm install and npm start I receive the following message:
> node-red@2.2.2 start
> node packages/node_modules/node-red/red.js

In fact, the address 1880 is already in use with a different instance of node-red. But what bugs me is that it's looking at the folder /home/user/.node-red/flows_lavos.json and not /home/user/.node-red2/flows_lavos.json. What am I missing? I'm sure that all .node-red words on Node-RED's source code were substituted by .node-red2. Is there any extra procedure or a different way of accomplishing the same?
