On one of my Ubuntu 11.10 servers, when I use sudo -i to become the root user, root's .bashrc is not being executed. On all other servers, whose relevant configurations are identical as far as I know, it is being executed properly.

Here's what I've checked:

• .bashrc exists in /root, owned by root:root, permissions 644


• /etc/profile and /etc/bash.bashrc are being executed


• root's shell is set to "/bin/bash"


• I can execute .bashrc with source .bashrc, after which everything is normal for that session.


• I can also type bash to execute bash manually after I've sudoed to root, and .bashrc is then executed


• ps confirms that the running shell for my root login is bash.

Anything else to check?
