This was discussed earlier and now that makefs has patches for UFS label support there should be no need to continue to use GPT partitioning for the memstick image. The background is that bsdinstall relys on labels (a good thing) and GPT partition labels were being used but as there's no way to predict the size of your memstick, the resulting GPT partition table was not valid (for strict UEFI systems). The fix was to go back to traditional MS-DOS partitioning (MBR) but this couldn't be done until makefs supported UFS labels. Someone came up with patches so 9.0 should be able to have an MBR memstick and bsdinstall. I'm not sure how far this has progressed.
