Each host needs a customized copy of the jumpstart script that contains the unique rootdisk name. So, there are 100 different copies of jumpstart scripts for 100 systems, even if there is only one disk on each system. > If there's > more > than one posible device, how do you specify which > one is > the root device?

Well, a system comes with a default rootdisk, which is suppposely known by the platform subsystem. In this case, the system can translate the generic rootdisk name to the corresponding physical device, with the help of the platform subsystem. That is where we see the possibility to automate the admin task. And the rootdisk won't be changed unless the admin liberally reconfigures it. How do we automate this step? We can't, and what's the point? lucy > > -- > -Peter Tribble > L.I.S., University of Hertfordshire - > http://www.herts.ac.uk/ > http://www.petertribble.co.uk/ - > http://ptribble.blogspot.com/ > > > __________________________________________________ Do You Yahoo!?
