After some comments from Greg Lehey during his kernel debugging tutorial, (to paraphrase, "you can save your panic to a UFS partition, but it won't be a UFS partition any longer"), I've been experimenting with the idea of a "panic partition" for dumpdevs. The purpose is to have a rapid reboot after a panic. Now, my laptop has a DOS sleep partition. Is it safe to use that as a dumpdev? I have to use 320meg for a sleep partition, and 321 meg for a dumpdev, when I could just use a 321-meg sleep/dump partition. It *seems* to work, but that means absolutely nothing in the real world.
