How is NFS enabled?
To enable NFS, it must be in busybox, RPC in uClibc and NFS support in the kernel then it all works well. According to one customer: “The latest buildroot may ignore the busybox config that is specified in the make menuconfig and ALWAYS copies the busbox.config from target/device/Gumstix/basix-connex. So you can either mess around with the buildroot Makefile or just modify the busybox.config in that directory. (I did the latter). This also applies to uClibc.config”. If you are planning to include support for nfs in busybox, you will also have to enable RPC in uClibc.config and NFS support in the kernel config as well and recompile the entire toolchain and buildroot.
