Assuming that disks are formatted, a stage3 has been freshly extracted,
bossman is installed, and the role/config files are on a mounted
filesystem, it should be similar to the role below:

    file /etc/portage/make.conf root:root 644
    ! emerge-webrsync
    ! emerge --sync

    file /etc/locale.gen root:root 600
    ! locale-gen

    pkg sys-kernel/gentoo-sources
    file /usr/src/linux/.config root:root 644
    ! make -C /usr/src/linux all modules_install install

    pkg sys-boot/grub
    ! grub-install /dev/sda # I can't remember all the options needed here
    file /etc/default/grub
    ! grub-mkconfig -o /boot/grub/grub.cfg

    # Generating /etc/fstab using something similar to Arch's `genfstab`
would be much better
    file /etc/fstab root:root 644

    # Root password
    file /etc/shadow root:root 640

    # Logger
    pkg app-admin/syslog-ng

    # Network
    pkg net-misc/dhcpcd
    enable dhcpcd

    # For remote access
    pkg net-misc/openssh
    file /etc/ssh/sshd_config root:root 600
    file /etc/ssh/known_hosts root:root 600
    # Other sshd files...
    enable sshd

There are a ton of assumptions that make this work; if installing
manually, the installer is responsible, and if installing from PXE, this
stuff would have to be baked into the ISO.

Automating the bootstrapping of a node is reasonably complicted, even
harder on Gentoo than on RHEL. This is the type of thinking I want to
do, and I'm working on doing this with my CentOS box that runs ssh,
Jenkins, postgres, and Redmine.
