|

Un nom de système correspond au nom d'un répertoire situé dans le
|
||||
sous répertoire "systems" de Vdn.
|
||||
|
||||
-h : affiche cette aide
|
||||
-b : execute le système en arrière plan.
|
||||
-d : mode DEBUG.
|
||||
-g : si l'interface graphique est démarrée, lui délègue le démarrage.
|
||||
-t : le terminal courant est utilisé en console.
|
||||
-e : Attendre "Entrée" si erreur.
|
||||
-v exp : évalue une expression. Pratique pour la surcharge de variables.
|
||||
exemple : -v "MEMORY=32; SWAP_SIZE=32"
