Subject line sums up the question. What I'm trying to do is to generate a "sender" initrd with cast-o-matic that mounts a partition (using cast-o-matic's "Other commands to be executed before transfer but after menu:") where image files are stored and then serve out the image files with udpcast.

Cast-o-matic is for configuring the "embedded system" to be booted on the system to be imaged.
Mounting partitions containing image files on the other hand is typically something you'd do on the server, not in the embedded system

I've been trying to use one system as both. I've got a PC with two hard drives; one used as the system drive for whichever operating system I want to boot and the other for storing the operating system/software image files. I've been able to use cast-o-matic sender images to do what I want but the process is a bit kludgy...press CTRL-C once I've gotten through the setup menu, go to one of the other consoles, create a mount point and mount the image drive, then start up udpsender with "--file" and serve out the image of choice. Part of the reason I've been doing it this way is that the server (on which I am not the admin) for the lab of PCs I'm managing is a Sun E250 running Solaris 9...do you know of anyone that's ported udpcast to Solaris for SPARC?

Hi Tom,
I'm not going to interrupt your interest in solving your issue with udpcast, but I feel that udpcast doesn't really fit your needs in your special case. udpcast hast been built for the purpose to transfer images from a server to one or many clients over the network via multicast (at least that is the case if I am using udpcast). I think you should use tools like "partimage", "dd_rescue" or "dd" to accomplish your task, since you just don't need the detour over the network. All you need is a LiveCD with the necessary tools on it like Knoppix. I think your issue can be solved with udpcast also, but I don't get why you should use it in that case.
Kind regards Jens
