|

Les grosses différences de chaque gestionnaire sont plutot philosophique :
|
||||||
|
\begin{itemize}
|
||||||
|
\pause
|
||||||
|
\item APT : Image de stabilité et de grand publique.
|
||||||
|
\begin{itemize}
|
||||||
|
\item + : Très stable, grosse communauté donc beaucoup de ressources dont en francais.
|
||||||
|
\item - : Souvent plus en retard sur des versions très recentes de certains logiciels.
|
||||||
|
\end{itemize}
|
||||||
|
\pause
|
||||||
|
|
||||||
|
\item DNF : Image de robustesse avec une image plus d'usage professionel
|
||||||
|
\begin{itemize}
|
||||||
|
\item + : Très robuste, moins de chance de casser le système même pour des configurations exotiques
|
||||||
|
\item - : Le processus de mise à jour peut être plus lent, et plus compliqué à prendre en main que APT.
|
||||||
|
\end{itemize}
|
||||||
|
\pause
|
||||||
|
|
||||||
|
\item PacMan : Minimaliste et ultra à jour.
|
||||||
|
\begin{itemize}
|
||||||
|
\item + : Systeme de "Rolling Release" qui permet d'avoir les mise à jour en continu.
|
||||||
|
\item - : Necessite un plus grand travail de veille sur les mise à jour.

||||||
