It did, but unfortunately that's still way too small for my freebsd-boot partition (which apparently is only 44kB large :/..): Before: $ ls -l `make -V.OBJDIR`/gptzfsboot -rw-r--r-- 1 ngie wheel 111662 Jan 28 11:00 /usr/obj/usr/src/sys/boot/i386/gptzfsboot/gptzfsboot After: $ ls -l `make -V.OBJDIR`/gptzfsboot -rw-r--r-- 1 ngie wheel 65371 Jan 28 11:05 /usr/obj/usr/src/sys/boot/i386/gptzfsboot/gptzfsboot Time to do some more tricks to pare down the bootloader size. Sidenote to the folks who drive the release notes and upgrade instructions for FreeBSD 12.x -- it needs to be clearly explained that gptzfsboot has grown considerably in size and mitigation instructions should be provided for updating gptzfsboot -- in particular with folks who might be using freebsd-update, so don't have the luxury of the choice of bootloader build options when upgrading.
