Thanks to this year's #Google #SummerOfCode (#GSoC), a student developer took the initiative in working on an automated #Gentoo #Linux system updater to help begineers and ease the roll-out of security updates to users. The default behavior with gentoo_update is to only deploy security updates from the Gentoo Linux Security Advisories (GLSA) by default. Alternatively the #gentoo_update utility can also keep all system packages up-to-date. https://www.phoronix.com/news/Automated-Gentoo-Updates better than cron'ing emerge!
