Re: Quelques infos supplémentaires SVP :-)

Le noyau est un 2.6.12-2-k7 (noyau standard de la debian testing)
Udev est en version 0.093-1.

Dmesg (rien de particulier, le baratin classique) :

Le lien que tu donnes est celui qui m'a servi à faire mes règles. C'est une bonne doc sur udev je trouve aussi...

Je vais explorer la piste que tu m'a donnée au sujet du nombre de partiches, je
vais en créer 4 ou 5 et voir si le nombre de RUNs change (actuellement j'en ai 2,
une en vfat et une en ext3 donc il devrait y avoir 3 appels :-(((
