grub2-mkconfig

[Patrick Dupre]

/dev/sdb1:Microsoft Windows XP Professional:Windows:chain
/dev/sdb6:Fedora release 16 (Verne):Fedora:linux
/dev/sdc1:Microsoft Windows XP Professional:Windows1:chain
/dev/mapper/VolGrpSys2-root:Fedora release 20 (Heisenbug):Fedora1:linux

The last one is OK, but it give grub.cfg:

menuentry 'Fedora release 20 (Heisenbug) (on /dev/mapper/VolGrpSys2-root)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-66528cb3-5298-4882-976c-02935cfac589' {
        insmod part_msdos
        insmod ext2
        set root='hd2,msdos6'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint-bios=hd2,msdos6 --hint-efi=hd2,msdos6 --hint-baremetal=ahci2,msdos6 --hint='hd2,msdos6'  ac2542fe-cd0b-4461-b656-965778d4a055
        else
          search --no-floppy --fs-uuid --set=root ac2542fe-cd0b-4461-b656-965778d4a055
        fi
        linux16 /vmlinuz-3.17.8-200.fc20.x86_64 root=/dev/mapper/VolGrpSys0-root ro vconsole.font=latarcyrheb-sun16 rd.lvm.lv=VolGrpSys0/root LANG=en_US.UTF-8
        initrd16 /initramfs-3.17.8-200.fc20.x86_64.img
}

why:
linux16 /vmlinuz-3.17.8-200.fc20.x86_64 root=/dev/mapper/VolGrpSys0-root ro vconsole.font=latarcyrheb-sun16 rd.lvm.lv=VolGrpSys0/root LANG=en_US.UTF-8
