After you recompile your kernel with encryption support, you might want
to use this line in '/etc/fstab' instead of using sudo:
"/home/haim/.crypto      /home/haim/crypto       ext2   
defaults,exec,noauto,loop,encryption=AES128,user,exec 0 0"
ofcourse it should be in one line. remember also to put "exec" after
"user" if you want to be able to run executeables from this file system.
