Eviter fsck au login, montage libpam_mount

Bonjour,

Je viens d'installer un montage au chargement de session via libpam_mount. les montages se montent là où il faut.

mais je me pose des questions sur une analyse disque qui lance à chaque premier montage du disque usb iomega . ca se produit au reboot apres le premier login et lorsque le montage dans le home est fermé. j'ai supprimé le partage /home/patrick/iomega et en revenant sur le compte j'ai les messages de debug :

en invalidant le partage dans /etc/security/pam_mount.conf.xml je n'ai aucun test : j'ai invalidé les montages automatiques au niveau de gnome ainsi qu'au niveau de la gestion des disques via la barre unity.

j'aimerais bien invalider ce auto check à reboot... je pourrais mettre une balise <fsck>none</fsck> dans la config /etc/security/pam_mount.conf.xml mais je considère ca comme du bricolage qui solutionne pas grand chose.

merci de vos réponses.

les messages de debug.
