On most of our servers, tab completion of service names after typing in the service command no longer works, as root. It works just fine as non-root. This is on Ubuntu 12.04. I'm not sure how to approach troubleshooting this.
Demonstrating:
Tab completion works as the normal user zachary, who pressed tab to list completions in the first image:
But as user root, it doesn't list services as completions (only files):
Any help would be greatly appreciated.
