I was talking about the MBR partitioning scheme versus GPT. gpart can create both, and of course newfs must be used regardless. The concern is whether boot0 can recognize GPT partitions. Probably not, but I have not tried it. >> Another option for GPT is to use the bootme and bootonce flags.

Some of the description of them in gpart was moved to the new gptboot man page. It was more relevant there, and is explained in more detail.
