Gentoo Net Boot

My upgraded server has no room for a DVD drive, so in order to install Gentoo, it had to be booted over the network. To do this I made a Gentoo installation in VMware Fusion on my Mac Pro. I then created a second Gentoo installation to be booted over the network in the VM's /diskless directory, roughly following this tutorial. The DHCP server at my particular location runs Tomato, which uses dnsmasq, requiring the following special parameters:The contents of /etc/conf.d/:

INTFTPD_OPTS="-R 4096:32767 -s ${INTFTPD_PATH} -l -p -c -vvvvvv -u ${INTFTPD_USER}"

I diverged from the Gentoo instructions again by using an initrd. The contents of /diskless/boot/grub/grub.conf:

title Diskless Gentoo Linux 2.6.31-gentoo-r6
root (nd)
kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r6 doscsi root=/dev/nfs ip=dhcp nfsroot=
initrd /boot/initramfs-genkernel-x86_64-2.6.31-gentoo-r6
