Hi.

	I noticed that I can't kldload nfsserver.ko like following:

on boot(rc script)

Clearing /tmp.
link_elf_obj: symbol sysctl__vfs_nfs_children undefined
linker_load_file: Unsupported file type
kldload: 
can't load nfsserver
: 
Exec format error
/etc/rc: WARNING: Unable to load kernel module nfsserver

	So I added following line and recompile:
