Putting the ip number in the root-path cures the | pxeboot failure. But is still only configure the NFS ROOT according | to the kernel's output. I had a look at the pxe code in | /sys/boot/i386/libi386/pxe.c where pxeboot is built from and in | /sys/i386/i386/autoconf.c which is the kernel side and it looks like | they don't do anything about swap. There is a /* XXX set up swap? */ | placeholder though. :-) Yep looks like you're right, I just tried it on 4.2-BETA it worked in 4.1.1. Swap is now broken ... sigh this is going to be a problem. I guess the only thing you might be able to do in the interim is to do a vnconfig of a file and then mount that as swap. I think the vnconfig man pages describes this. Hopefully it works over NFS.
