Nexenta currently lacks the ability to do automated network based installs via Jumpstart. The recent alpha6 version added KickStart ability, but it’s limited to CD based installs as far as I know. I am in the process of deploying multiple production machines at work and wanted to leverage my existing Jumpstart framework. I’ve managed to come up with a working solution that involves a Jumpstart begin script and debootstrap. All that’s really necessary for this is a standard SX:CR jumpstart miniroot, DHCP and TFTP server.
