To configure a client to receive a multicast stream:

$ sudo asr -source asr://<hostname> -target <targetvol> -erase

The client will receive the multicast stream from <hostname> and save it to a client. Add -eraseto overwrite any existing image. Passing -erasewith -targetindicates any existing image should be overwritten when doing a multicast.

Choosing a Boot Device Using systemsetup

You can use the systemsetup tool to choose your boot device. When setting the startup disk, you simply have to know the full path to core services. For example, to boot from “Disk 2,” which is now mounted in /Volumes, you would enter:

$ systemsetup -setstartupdisk /Volumes/Disk\ 2/System/Library/CoreServices
