Gentoo Linux Cron Update
Autor: Michael Panhorst
Oryginalny post:
http://forums.gentoo.org/viewtopic.php? ... 52#1304452
Wymagania: mailx, esearch, gentoolkit
Sposób instalacji: Najprostszy - umieszczenie skryptu w katalogu /etc/cron.weekly, inny - umieszczenie w crontabie.
Opis: Skrypt służy do automatycznego synchronizowania komputera(zalecane raz na tydzień - chodzi głównie o obciążenie serwerów rsync)
Co robi skrypt:
1. emerge sync
2. fixpackages, jeśli trzeba
3. Sprawdzenie GLSA
4. Jeśli wystąpiły błędy przy emerge sync albo są nowe GLSA, skrypt wysyła email z informacją
5. Sprawdzenie czy są nowe wersje (emerge system or emerge world)
6. Paczkowanie nowych wersji jeśli spełnione są zależności(emerge -B)
7. Wysłanie emaila (jeśli są pakiety do zaktualizowania), a także informacji w jaki sposób tego dokonać (używając juz skompilowanych paczek - emerge -avK)
