Ok, but from what I understood on lkml, 2.4.10 changed this didn't it ?

What I would like to know is if I can use NBD for my swapping.... As
Mark said if you need memory to start using NBD and if you need NBD
when you run out of memory (when you want to swap) it looks like we
 won't make it :(

Thanks for your help, I think I will search in the lkml archive too :)
