I am going working on adding Travis CI to my project. I am using the Nitrogen Travis file as a base. I noticed this line at the very bottom:
before_script: "sudo apt-get --yes --force-yes install libpam-runtime"
A Google search turned up this site with this description:
Contains configuration files and directories required for authentication to work on Debian systems. This package is required on almost all installations.
Do I need this line or is it Nitrogen specific?
