Hi Ralf

Thanks for that  i am also using syslinux for boot i fell out with grub
basically the root partition is a result of my cockup  i have several 1Tb
drives  i was going to use one of those as the root partition the entire drive

Just wish i had thought a bit more about it when i set the machine up  several
years ago now  you learn   , I will have to study  some . once again thanks
