I can triple-boot a cluster here... - OSCAR5 centos4.4 via normal channels, except it always network boots - the oneSIS NFSroot system into a centos4.4 via network boot with a different kernel and args and pointing it at the ro NFRroot dir - if I toggle tftp to point to 'DEFAULT localhost' then it boots from the local hard disk which has a SLES10 partition on it none of it's hard to do. BTW, NFSroot from oneSIS is read-only and light weight. people are running 200 clients in this way from a single NFS server. you can use multiple NFS server if you want to scale more, or run a Lustre root but OTOH Lustre isn't good with small files... SLES10 came pre-installed. I put on OSCAR5, and then made a copy of the OSCAR OS image as a starting point for the oneSIS setup. the oneSIS boot option is also great for diagnosing problems and fixing nodes as you don't use the local disk at all. cheers, robin >time.
