Hi everyone.

I was just wondering if anyone has tried making OpenWRT boot off a NFS mount?

eg. I have a WRT54GS which is currently running OpenWRT, and I wanted to make it have the / partition on my NFS server instead.

I know how to do this with "normal" boxes (x86 etc), but the WRT is quite limited, and I'm not entirely sure how to go about doing it.

I know that the kernel must have support for NFS Root, and either a DHCP server or the Boot loader must provide details of where the NFS share is, (i have only done it using the bootloader method on normal computers, and I'm not entirely sure if the bootloader in the WRT54GS would support this).

Anyone done this before or have any tips?

Hi !

Yes it is possible to do this, but not sure for WRT54xx devices.

Here is a nice work, running a fonera (atheros/redboot) with rootfs on NFS remote computer.
OK, it's written in japanese and made from DD-WRT ! But with a lot of details, including how to configure the kernel for NFS boot.

You can adapt to OpenWRT I guess, perhaps g00gle may help you in other language?

Regards.
