Dan, There is no documentation anywhere on doing brand development. If you look in the smartos-live repo at overlay/generic/usr/lib/brand/lx/lx_boot_zone_ubuntu you can see the SmartOS-specific things we do during the boot of ubuntu. There is a slightly different and more generic version of that file in the illumos-joyent tree which is more suitable for upstreaming in the future. I haven't looked to see what init is being used on centos but if you can get the zone to boot so that init stays up and running then it becomes much easier to move forward. You can zlogin to interact with init, you can dtrace in the GZ while init is coming up, etc. Getting init to stay up and then up to multi-user is the biggest hurdle when when you are working with a new release inside lx. This is because the newer Linux init's, like upstart or systemd, are using various obscure parts of their kernel to try do all sorts of things. Feel free to ping me with specific questions but there is no guide to doing this, it is just a lot of tough debugging.
