AI is invoked by doing "boot net:dhcp". However, as Jan pointed out, since the boot device is set to disk upon a successful sparc install, accidental reboot resulting in AI is less of an issue. > So an accidental reboot off the network shouldn't be an issue. > > x86: > > The problem here is that there isn't a way to toggle the install > behaviour.

So, how about having such a setting in the AI manifest that works in conjunction with the AI client to provide the "just install this version of the OS once on this client" behavior? Would something like that work? Alok
