>Description:
I want to use the pxeboot loader to use an mfsroot as root, not an nfs mount.
In /usr/src/sys/boot/i386/libi386/pxe.c line 340, the function pxe_setnfshandle always gets called. If you don't have an nfs server running, the loader gives the error "NFS MOUNT RPC Error". It continues loading the mfsroot over tftp though.
>How-To-Repeat:
              
>Fix:
Can the option to do the rpc mount be made a compile time switch? This would be great for everyone who doesn't need the nfs mount option for diskless clients.
