                Pacman Automatic Updates
              
          
    Background

I may have let Arch go months without updates before.  Its not advisable to apply them on a schedule either.
Solution

Providing regular prompts to apply updates seems like the best solution.
Schedule Download of Packages

This cronjob will download packages and cache locally.  Put into root's crontab or run via sudo.
