Hello Luggers,
Does anyone know how to do = a NFS mount WITHOUT using tftp or dhcp or bootp?
I have a kern= el compiled on a client machine having NFS support. I have a Embedded= root filesystem ready on the Nfs server and I have already exported its co= ntents.
portmap, nfsd and mfslock are running on the Nfs serve= r.
Now, if I mistake not, by passing appropriate arguments to = the bootloader (i.e.Grub in my case), we can make the kernel from the clien= t machine boot and mount the remote root filesystem(residing on the server)
Is this actually possible? Can anyone provide me the l= inks?
Raseel.

Hi Raseel,
Usually this is a bad idea.
You can have the nfsroot put up in the kernel command line.
append root=/dev/nfs nfsroot=a.b.c.d:/path/to/nfs/root/on/the/nfs_server/
Look at this page : http://www.tldp.org/HOWTO/Diskless-root-NFS-other-HOWTO-4.html

Why is this a bad idea ?? I think it is a fairly good idea if you are using embedded systems or thin-clients. Other than the performance hits due to NFS over udp. (you can configure nfs to work over tcp as well), there should not be any other disadvantage.
Hey Vinayak,
append root=/dev/nfs nfsroot=a.b.c.d:/path/to/nfs/root/on/the/nfs_server/

Its a bad idea as you can see, you need to hardcode this into the kernel source code for the command line (unless you have good boot loader, grub is one, but i didnt have success in putting up Grub, the stages file size are too big for embedded systems ), and something that is hardcoded is certainly not good.
But yes it is a good idea if you have thin clients and that you know the IP of NFS Server and the path is never going to change. Choice is yours :)
