Browse files Browse the repository at this point in the history 
- [x] install for another user by setting environment variable e.g. `NODERED_USER=test`
- [x] suggest user `nodered` during install when environment variable `NODERED_USER` is not set.
- [x] comment low memory NODE OPTIONS
- [x] correct environmentFile, to /etc/node-red/environment
- [x] add some color to differentiate users
- [x] can be started as root or normal user, will prompt for password for sudo
