 Hi Ceri,
 
 It does indeed do what I want, but the issue is that it takes a while for
 pxeboot to notice that it can't mount nfs.
 Since I compiled the loader with LOADER_TFTP_SUPPORT, I don't think it
 should try to do an rpc call in the first place.
 This slows down the booting process. Although the nfs mount error is
 harmless, it makes people (like me) think there's something wrong.
 
 If my memory is right, it behaved ok before patch 1.21 (
 http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/boot/i386/libi386/pxe.c.diff?=
 r1=3D1.20&r2=3D1.21
 )
 
 Cheers,
 
 Ruben
