[Résolu] installation chiffrée de Ubuntu 13.10

J'ai mis "Résolu" dans le titre parce que je n'attends pas d'aide : je voulais juste tester la chose et laisser quelques traces de ce test.
Les conditions : essai en simulation avec VMware player. Installation en mode EFI sur disque dur ayant une table de partition GPT avec un liveCD (virtuel) de Ubuntu 13.10 64bits.
Choix à l'installation :

Il faut cocher la case "Chiffrer...". Le fait ce cocher cette case entraîne que la case Utiliser LVM est cochée automatiquement  :
mini_331539Capturedu20131206113757.png
A noter : on ne peut cocher cette case "Chiffrer..." que si "Effacer le disque et installer Ubuntu" est sélectionné. Si c'est "Autre chose" qui est sélectionné, la case "Chiffrer..." est grisée (on ne peut pas la cocher) 
Voilà ce que ça donne après installation (avec l'application "disk") :
