Note: This version of the VDT (1.9.1) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.
The vdt-update-certs script is designed to help keep your CA Certificates up to date. It runs out of cron, and will check for a new certificates package once per day. This mechanism is compatible with Pacman, and you can later use 'pacman update' to update your CA-Certificates package.
Use Pacman to install the CA-Certificates-Updater package. At install time, a prompt will ask if you want to automatically update your certificates. After install, you can run $VDT_LOCATION/vdt/setup/configure_ca_cert_updater --server [y,n] to turn the cron job on or off.
