As long as no one expects the dump format to be static, we should have no problem as we migrate to desDUMP. What are the features missing from our older dump formats that are required -- the ability to sparsely store chunks of address space, etc? (Note: it would be very cool to be able to swap a hard disk from a sparc64 box to an i386 box, and have savecore dump the core from it to a system dump, then have cross-compiled gdb debug it. Of course, we have other problems before then -- are our disk labels endian-aware?)
