Unhappy triying to make a diskless server


hi everyone, I want to serve diskless clients linux (any distribution), and everithing I found leads to netboot. Everithing is fine so far, since I managed quite well to set up the NFS, tftp, and bootp services required to do this, I even compiled the required kernel image including booting over NFS and NFS built in this kernel image...
The question is: what I first want to try is to boot this image using a diskette with grub and this kernel image (having it processed by mknbi, which is a tool included in the netboot package to MaKeNetBootableImages), but the thing I don't know is: how do I tell the kernel to look for its root filesystem on the NFS server?? (considering that the normal grub line looks like kernel=/boot/vmlinuz root=/dev/hda ro)

if anyone did this yet, cuold be of great help, since all the documentation I found is either inclomplete or does not work (or even worse, I do not understand it!!! )

Thanx

Thumbs up

Thanx for the Info, I'll go there since i got pretty tired of netboot...
anyway, I found the grub kernel parameters to boot from a diskette, or a tiny HD or a cdrom...

root (fd0)
kernel=/vmlinuz root=/dev/nfs \
nfsaddrs=<client-ip>:<server-ip>:<gateway-ip>:<subnet-mask>\
:<client-hostname>: nfsroot=/<nfs-share>

all this considering the kernel has been compiled with nfs and NIC driver builtin and nfs-share is a / susbtitute, suitable for booting, chroot jail

greets!!

Take a look at 2X

It sounds like you're trying to assemble all of the parts piecemeal. A better way might be to try X2, found at www.X2.com.

They offer a complete system for FREE with installation instructions. You might save yourself some time and aggravation.

Cheers!
