4. Installation d'OpenBSD

Lors de la sélection des paquets à inclure à l'installation, j'ai volontairement supprimé tous les paquets X server. En effet, l'APU4D4 sera utilisé comme firewall, il n'est donc pas nécessaire de garder ces paquets.

Select sets by entering a set name, a file name pattern or 'all'. De-select
sets by prepending a '-', e.g.: '-game*'. Selected sets are labelled '[X]'.
    [X] bsd           [X] base69.tgz    [X] game69.tgz    [X] xfont69.tgz
    [X] bsd.mp        [X] comp69.tgz    [X] xbase69.tgz   [X] xserv69.tgz
