I've tried by changing my.machine.int into an ip address and the debug 
console tells me there is a command that anaconda doesn't understand 
(but it didn't tell me which). I'm wondering if it there would be 
another method to include script without using nfs mounts ?

PS : here is my /etc/exports (I use the second export) :
/var/kickstart/ 192.168.0.0/255.255.255.0(rw,no_root_squash,sync)
/var/kickstarttest/ 192.168.0.0/255.255.255.0(rw)
