Siempre es bueno darse una vuelta al wiki de Manjaro, hasta hace unos días estaba bastante cómodo actualizando mi sistema con el método tradicional usando pacman sudo pacman -Syyu.
Pero descubrí el script en Bash Allservers que le da otra vuelta a la tuerca y automatiza varias tareas importantes dentro de la forma de actualizar Manjaro.
Por ejemplo:
- Actualiza la lista de los mirrors más recientes de Manjaro y esto es importante porque constantemente se dan de alta nuevos o dejan de funcionar otros.
- Crea una lista de los tres mejores mirrors basándose en su velocidad (rankmirrors).
- Sincroniza la base de datos de paquetes.
- Actualiza el sistema base y los paquetes AUR.
- Limpia el cache de paquetes usando el script cacheclean que elimina paquetes antiguos pero deja las dos últimas versiones. Esto es muy útil, porque ahorramos espacio, pero guardamos un par de paquetes por si algo sale mal y queremos hacer una desactualización (downgrade).
Alservers necesita que instalemos primero el paquete cacheclean
yaourt -S cacheclean
Luego descargamos el script (copiar y pegar) y lo guardamos en el un archivo de nuestro home:
#!/bin/bash
# 27-April-2013: Updated to use the new pacman-mirrors -g to rankmirrors. :)
#
# allservers.sh - inspired by Manjaro's Carl & Phil, initially hung together
# by handy, the script's display prettied up & progress information added by Phil,
# the menu & wiki page added by handy.
# Latest revision now calls everything via the menu.
# The following wiki page is about this script:
# http://wiki.manjaro.org/index.php/Allservers.sh_Script:-_Rankmirrors,_Synchronise_Pacman_Database
# Following wiki page will introduce CacheClean & related information:
# http://wiki.manjaro.org/index.php/Maintaining_/var/cache/pacman/pkg_for_System_Safety
#___________________________________________________________
#
# allservers.sh is now completely menu driven. The Menu describes
# what it does for you, if you need more detail see the two
# wiki page links listed above.

Para darle permisos de ejecución, en una terminal tecleamos:
chmod +x ./allservers.sh
Para ejecutar el script Allservers:
sudo ./allservers.sh
Y elegir alguna de las opciones del menú.
Simplemente la actualización de mirrors y su calificación hacen que este script valga la pena.
Actualización 27-abr-2013
Hubo una actualización a este script, usa la nueva estructura de paquetes y el comando pacman-mirrors -g para actualizar y calificar los mejores mirrors para Manjaro.

Si su sistema tiene instalado pacman 4.1 (o superior) probablemente les convenga usar este script en lugar del anterior.
Sólo tengo una pregunta, por qué sacar fotos a la pantalla cuando se pueden hacer screenshots? Epic wtf!
Pues no se a que te refieres, las imágenes son screenshots de la terminal.
hola, muy bueno el texto sobre la actualización de Manjaro. saludos, Holmes
