Won't be the next time , i just got a copy of doom3 for linux , so came
up with an idea for the cool sound .. i know it's a big security problem
, i'm not gonna merge it into my system.
BTW: by default cryptsetup try 3 times before a user type in the right
code , is there any way to make it check only once ?
( if i'm not using a shell pipe in system() passing my password )
Thanks !
