Overview

This "root" module simply define few preferences for the root user.

Setup

What root affects

• Root's configuration files (/root/.profile, /root/.bashrc,…).
• Root's mail can be forward to other addresses.

Beginning with root

To begin using root module with default parameter, declare the class with include root.

Usage

Exec ZSH for some clients

To autoload ZSH as "default" shell, you can pass a regex to the IP_ZSH argument. Then for every new connection, the .profile file will compare the $SSH_CLIENT variable environnment with this regex :

class { 'root':
  ip_zsh => "(10.10.10.1|192.168.0.42)",
}

Other default shell

Bash is the default shell use on Debian, if you prefer an advanced shell or didn't have Bash, you can define the DEFAULT_SHELL_PATH argument :

class { 'root':
  default_shell_path => '/bin/zsh',
}

Then, every connection from 10.10.10.1 or 192.168.0.42 will automatically have ZSH as default shell.

Forward mail

Root's mail can be forward to other addresses. You can specify thoses addresses with the ADDRESS_TO_FORWARD argument :

class { 'root':
  address_to_forward => 'username@domain.org,firstname.lastname@other-domain.org',
}
