Hello everybody,

I just wanted to know if there is a plan to include PXE-diskless boot with all root system filesystem on NFS, like with pxeboot or the system-config-netboot of Centos/Redhat.

Benefits would be :
- quick boot-time, no need to download the complete system image
- easy to maintain/backup, a NFS readonly tree for common system/application files, and a NFS read-write tree for specific per-server files
- consistancy/update, even when cluster is running, adding/moddifying a file in the common tree (even rpm install with chroot), would update it immediately on all nodes, no need to check on nodes for the change or reconstruct/reboot the image.

Drawback :
- Network dependant : if the NFS server fail, all nodes impacted, must be dual headed (netapp) or clusterred
- should not have intensive disk IO.

With the "system image" node installation, all is almost done in kusu, it just lacks the pxe/initrd part.

I certainly forgot other drawbacks, but for my point of view, the missing part is very small, and the benefits would be great.

my two cents... xav'
