Hmm; not good for the long term. Although a hack and potentially disastrous if not handled carefully, hybrid MBR really is necessary under certain conditions. Perhaps support should be read-only by default, with a means to switch to write, and dire warnings that one is likely severely to break things if one isn't careful? Although it could be argued that those likely to be playing with fdisk (rather e.g. than Partid) might be expected to know what they're doing. :D To be honest, I'd like to see a means completely to separate GPT/MBR changes, so if necessary one could do absolutely anything to either without affecting the other. If somebody is playing around with both, then really they should expect to understand what will happen if they're careless.
