Paul is right, but you shouldn't need to modify anything. Here's what |
| 22 |
grub2-mkconfig generates on my machine (first entry only): |
| 23 |
|
| 24 |
|
| 25 |
menuentry 'Gentoo GNU/Linux' --class gentoo --class gnu-linux --class |
| 26 |
gnu --class os $menuentry_id_option |
| 27 |
'gnulinux-simple-713f1c17-1b9a-4967-ac05-d6a6a9ff60a5' { |
| 28 |
load_video |
| 29 |
set gfxpayload=keep |
| 30 |
insmod gzio |
| 31 |
insmod part_gpt |
| 32 |
insmod ext2 |
| 33 |
set root='hd0,gpt2' |
| 34 |
if [ x$feature_platform_search_hint = xy ]; then |
| 35 |
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 |
| 36 |
--hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 |
| 37 |
e39917c2-b59e-4447-bcae-39a41c3816a7 |
| 38 |
else |
| 39 |
search --no-floppy --fs-uuid --set=root |
| 40 |
e39917c2-b59e-4447-bcae-39a41c3816a7 |
| 41 |
fi |
| 42 |
echo 'Loading Linux x86_64-3.3.5-gentoo ...' |
| 43 |
linux /kernel-genkernel-x86_64-3.3.5-gentoo |
| 44 |
root=UUID=713f1c17-1b9a-4967-ac05-d6a6a9ff60a5 ro |
| 45 |
echo 'Loading initial ramdisk ...' |
| 46 |
initrd /initramfs-genkernel-x86_64-3.3.5-gentoo |
| 47 |
} |
| 48 |
|
| 49 |
|
| 50 |
And here are the file in /boot |
| 51 |
# find /boot/ -name "*genkernel*" |
| 52 |
/boot/kernel-genkernel-x86_64-3.3.5-gentoo |
| 53 |
/boot/System.map-genkernel-x86_64-3.3.5-gentoo |
| 54 |
/boot/initramfs-genkernel-x86_64-3.3.5-gentoo |
| 55 |
/boot/kernel-genkernel-x86_64-3.3.5-gentoo.old |
| 56 |
/boot/System.map-genkernel-x86_64-3.3.5-gentoo.old |
| 57 |
/boot/initramfs-genkernel-x86_64-3.3.5-gentoo.old |
| 58 |
|
| 59 |
It boots perfectly fine using my initramfs |
