Along with parsing /boot/loader.conf, /boot/device.hints and friends. Lastly it even has code to mount each of your BEs and copy the resulting grub.cfg file into each, so that you have a unified menu regardless of which BE you are currently booting. One thing that I really want to fix is detecting which kernel modules have what depends. Currently I have to ensure that /boot/loader.conf has both the target module + depends in order for GRUB to load them properly. If anybody wants to help hack on these and make them more "FreeBSD generic" I think it could eventually go into the ports tree for everybody. When grub-mkconfig is run, it generates a ZFS / BE specific boot-script, with entries that look like this: --------------------------------------------------------------- submenu "PC-BSD (default) - 2013-08-27 14:23" { menuentry "Normal Bootup" { insmod zfs search -s -l tank1 kfreebsd /ROOT/default/@/boot/kernel/kernel kfreebsd_module /ROOT/default/@/boot/zfs/zpool.cache type=/boot/zfs/zpool.cache set kFreeBSD.vfs.root.mountfrom=zfs:tank1/ROOT/default kfreebsd_module_elf /ROOT/default/@/boot/kernel/siis.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/sdhci.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/geom_journal.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/geom_mirror.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/geom_eli.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/aesni.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/zfs.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/tmpfs.ko kfreebsd_module_elf /ROOT/default/@/boot/modules/nvidia.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/dummynet.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/ipfw_nat.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/ipdivert.ko kfreebsd_module_elf /ROOT/default/@/boot/modules/vboxdrv.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/zlib.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/opensolaris.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/linux.ko kfreebsd_module_elf /ROOT/default/@/boot/kernel/crypto.ko set kFreeBSD.hint.fdc.0.at=isa set kFreeBSD.hint.fdc.0.port=0x3F0 set kFreeBSD.hint.fdc.0.irq=6 set kFreeBSD.hint.fdc.0.drq=2 set kFreeBSD.hint.fd.0.at=fdc0 set kFreeBSD.hint.fd.0.drive=0 set kFreeBSD.hint.fd.1.at=fdc0 set kFreeBSD.hint.fd.1.drive=1 set kFreeBSD.hint.atkbdc.0.at=isa set kFreeBSD.hint.atkbdc.0.port=0x060 set kFreeBSD.hint.atkbd.0.at=atkbdc set kFreeBSD.hint.atkbd.0.irq=1 set kFreeBSD.hint.psm.0.at=atkbdc set kFreeBSD.hint.psm.0.irq=12 set kFreeBSD.hint.sc.0.at=isa set kFreeBSD.hint.sc.0.flags=0x100 set kFreeBSD.hint.uart.0.at=isa set kFreeBSD.hint.uart.0.port=0x3F8 set kFreeBSD.hint.uart.0.flags=0x10 set kFreeBSD.hint.uart.0.irq=4 set kFreeBSD.hint.uart.1.at=isa set kFreeBSD.hint.uart.1.port=0x2F8 set kFreeBSD.hint.uart.1.irq=3 set kFreeBSD.hint.ppc.0.at=isa set kFreeBSD.hint.ppc.0.irq=7 set kFreeBSD.hint.atrtc.0.at=isa set kFreeBSD.hint.atrtc.0.port=0x70 set kFreeBSD.hint.atrtc.0.irq=8 set kFreeBSD.hint.attimer.0.at=isa set kFreeBSD.hint.attimer.0.port=0x40 set kFreeBSD.hint.attimer.0.irq=0 set kFreeBSD.hint.wbwd.0.at=isa set kFreeBSD.hint.psm.0.flags=0x1000 set kFreeBSD.kern.ipc.shmseg=1024 set kFreeBSD.kern.ipc.shmmni=1024 set kFreeBSD.kern.maxproc=10000 set kFreeBSD.legal.intel_ipw.license_ack=1 set kFreeBSD.legal.intel_iwi.license_ack=1 set kFreeBSD.vfs.zfs.prefetch_disable=1 set kFreeBSD.hint.acpi_throttle.0.disabled=1 set kFreeBSD.machdep.disable_mtrrs=1 set kFreeBSD.kern.geom.eli.visible_passphrase=2 } -- Kris Moore PC-BSD Software iXsystems
