[Udpcast] can cast-o-matic's "Device to be copied" be ignored or bypassed?

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. -- Tom Carpenter Computer Systems Specialist Biology 347 Morrill 611 North Pleasant Street Amherst, MA 01003-9297 phone: 413-577-2311 fax: 413-545-3243 email: tomc@bio.umass.edu
