This reminds me of a related suggestion / request. boot0cfg should be smarter, and require confirmation (unless forced) before overwrite a disklabel with an MBR (boot0cfg -b /dev/ad0s2g or similar). I believe overwriting a disklabel is much more likely to be pilot error, as in my case, than an deliberate choice. boot0cfg.8 says: > On PCs, a boot manager typically occupies sector 0 of a disk, which is > known as the Master Boot Record (MBR).
