Das Installieren und Deinstallieren der Pakete übernimmt ebenfalls Yast. Hier können Sie die vorhandenen Pakete nach Stichwörtern durchsuchen und so die gewünschte Software zum Nachinstallieren finden. Weitere notwendige Pakete wählt das Installationprogramm automatisch mit aus. Umgekehrt entfernt Yast nicht mehr benötigte Pakete auch wieder.
Natürlich holt Yast auch Pakete aus dem Internet. Sie müssen nur die richtige Adresse eingeben.

%description
This is a virtual RPM package.  It contains no
actual files.  It uses the 'Provides' token from RPM 3.x and later to list many of the sharedlibraries that are part of the base operating system and associated subsets for this $OS environment.

#Note that rpmbuild has replaced rpm. 
#The old RPM commands often still work,
