Not really: currently neither of them will work on the root file system. I'm planning to do it with Vinum, and when I do, it won't create boot problems (well, you're going to have to find out where a usable boot partition is, but that's all). > Would I have to use some magic to get the mirrored drive working as > the primary, or should I just need to make it the boot device? When I'm done, you'll just have to make it the boot device.
