Document RB_TIMEBAD. RB_DFLTROOT, RB_INITNAME, and RD_RDONLY are unimplemented or the default; documenting them is pointless and just makes this page harder to read.
I'm inclined to suggest deleting from sys/reboot.h the #defines for the unused options, including the three above as well as RB_SERCONS and RB_MINIROOT. Opinions?
