GRUB2 a FreeBSD - upresneni + pokusy

[Jan Dušátko]

Ahoj

Prikladam vysledky pokusu a rozsahlejsi popis problemu a jejich duvodu.
Pri bootovanim FreeBSD v GRUB2 nedojde k interpretaci
dat ulozenychv /boot/loader.conf, tzn. settings a nacteni dalsich modulu.
Potrebuji grub z duvodu snadne volby zalozniho boot prostredi. 

/boot/grub/grub.cfg obsahuje

        insmod ufs2
        set root='(/dev/ar0,1,a)'
        search --no-floppy --fs-uuid --set 4dad96ad553bd910
        echo                    Loading kernel of FreeBSD kernel ...
        kfreebsd                /boot/kernel/kernel
        kfreebsd_loadenv        /boot/device.hints
        kfreebsd_module_elf     /boot/kernel/acpi.ko
        set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ar0s1a
        set kFreeBSD.vfs.root.mountfrom.options=rw

/boot/oader standardne interpretuje nasledujici soubory
	/boot/device.hints
	/boot/loader.conf
	/boot/loader.conf.local

Resil jste to nekdo ?
Jeste doplnim par pokusu a jejich vysledky

menuentry "FreeBSD, Primary Boot Environment kernel" --class freebsd --class
bsd --class os {

        insmod ufs2
        set root='(/dev/ar0,1,a)'
        search --no-floppy --fs-uuid --set 4dad96ad553bd910
        echo                    Loading kernel of FreeBSD kernel ...
        kfreebsd                /boot/kernel/kernel
        kfreebsd_loadenv        /boot/device.hints
        kfreebsd_module_elf     /boot/kernel/acpi.ko
        set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ar0s1a
        set kFreeBSD.vfs.root.mountfrom.options=rw
}

Ignoruje /boot/loader.conf a /boot/loader.local


menuentry "FreeBSD, Primary Boot Environment kernel environment test"
--class freebsd --class bsd --class os {

        insmod ufs2
        set root='(/dev/ar0,1,a)'
        search --no-floppy --fs-uuid --set 4dad96ad553bd910
        echo                    Loading kernel of FreeBSD kernel ...
        kfreebsd                /boot/kernel/kernel
        kfreebsd_loadenv        /boot/device.hints /boot/loader.conf
/boot/loader.conf.local
        kfreebsd_module_elf     /boot/kernel/acpi.ko
        kfreebsd_module_elf     /boot/kernel/if_tun.ko
        kfreebsd_module_elf     /boot/kernel/ichsmb.ko
        kfreebsd_module_elf     /boot/kernel/ipmi.ko
        kfreebsd_module_elf     /boot/kernel/ichwd.ko
        kfreebsd_module_elf     /boot/kernel/zfs.ko

        set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ar0s1a
        set kFreeBSD.vfs.root.mountfrom.options=rw
}

Ignoruje /boot/loader.conf a /boot/loader.local, nenacte se acpi a ichsmb.
Jinak projde.

menuentry "FreeBSD, Primary Boot Environment kernel environment & module
test" --class freebsd --class bsd --class os {

        insmod ufs2
        set root='(/dev/ar0,1,a)'
        search --no-floppy --fs-uuid --set 4dad96ad553bd910
        echo                    Loading kernel of FreeBSD kernel ...
        kfreebsd                /boot/kernel/kernel

        set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ar0s1a
        set kFreeBSD.vfs.root.mountfrom.options=rw
}

Zhavaruje pri inicializaci, nenajde disky

menuentry "FreeBSD, Primary Boot Environment ordinal test" --class freebsd
--class bsd --class os {

        insmod ufs2
        set root='(/dev/hd0,1,a)'
        kfreebsd /boot/loader
}

Spusti se loader a ten nedokaze najit diskovy prostor.

menuentry "FreeBSD, Primary Boot Environment shotgun test" --class freebsd
--class bsd --class os {

        set root='(/dev/hd0,1,a)'
        chainloader +1
}

Není schopen zavest ani loader
