Got the following error building from Feb.15 -current sources:

ld -n -Ttext 0 -e start -x -o netbsd ${SYSTEM_OBJ} vers.o
nfs_vfsops.o: Undefined symbol `_nfs_boot_getfh' referenced from text segment
nfs_vfsops.o: Undefined symbol `_nfs_boot_getfh' referenced from text segment
*** Error code 1

Stop.

Seems like someone forgot to create a dummy nfs_boot_getfh() routine in 
the case when NETHER = 0 (as it does in my config).  The following patch 
creates the dummy routine, in the same way that it does for nfs_boot_init()
