https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227808 --- Comment #22 from vmiller@verisign.com --- FWIW, one can workaround this problem by deploying a bootonly ISO configured with an MFS_IMAGE. EFI_STAGING_SIZE may need adjusting to accommodate larger objects; It defaults to 64. EFI_STAGING_SIZE can be defined within make.conf, release.conf, or on the command line. While not illustrated below, EFI_STAGING_SIZE is implicitly defined specifying a make.conf that includes the knob in the environment via MAKE_CONF. MFS_IMAGE is necessary because the project’s bootonly ISO fails to PXE boot at mountroot() w/ error 19 indicating the boot media cannot be located. The hardware platform is HP DL360g9 in UEFI boot mode. MFS_IMAGE implies a MD_ROOT root filesystem. The build system doesn't seem provide a mechanism to build a default MFS_IMAGE and is therefore done outside the context of a build. The following procedure builds a binary distribution from the source tree in it's default form (including the default bootonly.iso). It rebuilds the bootonly.iso after generating a root partition and MDROOT kernel. # Create CHROOTDIR w/ GENERIC kernel (also builds binary release) root # cd ~/projects/freebsd root # git checkout releng/11.2 root # release/release.sh -c release/release.conf # Create root.part from ${OBJDIR} bootonly root # cd ${CHROOTDIR}/usr/obj/usr/src/release root # rm bootonly/boot/kernel/kernel root # rm bootonly/boot/geom_md.ko root # echo "/dev/ufs/FreeBSD_Install / ufs rw 0 0" > bootonly/etc/fstab root # makefs -B little -o label=FreeBSD_Install root.part bootonly/ root # cd .. && mkdir -p sys/MDROOT root # mv release/root.part sys/MDROOT/ # Build MDROOT kernel root # cat ${CHROOTDIR}/usr/src/sys/amd64/conf/MDROOT include GENERIC ident MDROOT makeoptions MFS_IMAGE=root.part root # eval chroot ${CHROOTDIR} env KERNCONF=MDROOT make \ -C /usr/src buildkernel # Build bootonly ISO w MDROOT kernel root # mount -t devfs devs ${CHROOTDIR}/dev root # chflags -R noschg ${CHROOTDIR}/usr/obj/usr/src/release/bootonly && \ rm -rf ${CHROOTDIR}/usr/obj/usr/src/bootonly root # eval chroot ${CHROOTDIR} env KERNCONF=MDROOT \ NOPKG=1 NOSRC=1 NODOC=1 NOPORTS=1 make -C /usr/src/release bootonly.iso -- You are receiving this mail because: You are the assignee for the bug.
