NetBoot with JAMF’s NetSUS Vmware Appliance

My regular NetBoot server is bumping up against a bug in Server 10.8 whereby tftpd errors out after about 10 clients boot, so yesterday we stood up a copy of JAMF’s free-to-use NetSUS appliance. Everything has been smooth (except a DNS hiccup) until we actually attempted to boot a client this morning, and the process crashed.

Turns out DeployStudio assistant builds NBIs with a sparseimage for the boot disk. Following up on this tip from Chris George, I converted that sparseimage to a standard compressed DMG, et voilá! Successful boot, and two processes (NetBoot and Apple SUS) that I can remove from my aging Xserve.
