I think you missed the point here. What is being requested is the 
partitioning dialog from sysinstall to be included in bsdinstall. The 
bsdinstall partitioning dialog should inform users about the differences 
between older and newer PCs and offer options to auto-configure the H.D 
appropriately. Or better yet have bsdinstall check the hardwares bios to 
determine if the bios are UEFI aware and what methods can be used to 
partition. The key here is that bsdinstall should provide at least the 
same level of automation as sysinstall has on this subject.
