John, all the recent versions of SystemImager supports heterogeneous hardware, as you said via udev, hotplug and discover.
The disk naming problem has been resolved adding the --autodetect-disks option to si_mkautoinstallscript (and si_getimage). So, the only problem now is that the documentation must be updated... ;-) Regards, -Andrea John Goerzen wrote: > Hello, > > I have just started reading about SystemImager.
