 I thought about that.  Having both GEOM_PART_MBR and GEOM_MBR
 seemed suspicious, but GEOM_PART_MBR isn't from the config file:
 
 grep -i geom GENERIC
 options         GEOM_PART_GPT           # GUID Partition Tables.
 options         GEOM_LABEL              # Provides labelization
 
 and then I added GEOM_MBR and GEOM_BSD as suggested.  So I don't
 know where GEOM_PART_MBR comes from or how to get rid of it.
 I am assuming that "make buildkernel" calls config(8) and config
 builds opt_geom.h based on the config file, but it must have some
 other input that I haven't found.
 
 It isn't clear to me what the difference between GEOM_PART_MBR and
 GEOM_MBR is supposed to be (same for GEOM_PART_BSD and GEOM_BSD).
 conf/NOTES doesn't list a GEOM_GPT, only GEOM_PART_GPT.  I assume
 that removing GEOM_PART_GPT would break disks using GUID partition
 tables.
