Generating ISO With Pre-Installed Packages

[Shawn Webb]

Hey All,

I'm looking to generate a FreeBSD 9-stable (and maybe 10-current) ISO that
has certain packages pre-installed. I'd like to create my own installation
media that will have certain things installed, like a web management UI
that I'm actively working on. It'd be like what pfSense does.

I did do a little googling and found pfSense's build documentation for
spinning a custom build of pfSense. I'll be spending the weekend looking
over their work. But in the meantime, does anyone know of the steps
involved in such a process? Is the process documented somewhere?

Thanks,

Shawn
