 |
|
Official migration guide: http://www.gentoo.org/doc/en/grub2-migration.xml
Well, the official guide did not work for me. So I just converted my grub.conf to a working grub.cfg without mkconfig and now want to share the results.
My SSD layout:
| Code: | /dev/sda1 /boot ext2
/dev/sda2 / ext4
/dev/sda3 /home ext4
|
/boot/grub/grub.conf
| Quote: | default 0
timeout 0
hiddenmenu
splashimage=(hd0,0)/grub/splash.xpm.gz
title Gentoo Linux 3.x Enterprise
root (hd0,0)
kernel /bzImage root=/dev/sda2 splash=silent,fadein,theme:enterprise CONSOLE=/dev/tty1 quiet
initrd /fbsplash-enterprise |
/boot/grub/grub.cfg
| Quote: | default=0
timeout=0
menuentry 'Gentoo Linux 3.x Enterprise' {
root=hd0,1
linux /bzImage root=/dev/sda2 splash=silent,fadein,theme:enterprise CONSOLE=/dev/tty1 quiet
initrd /fbsplash-enterprise
} |
Worked for me and fits nicely in my kernel update workflow (make, make modules_install, copy new bzImage to boot).

I used to always do it that way, but I've switched to letting genkernel build & install the kernel (using custom .config), then I run grub2-mkconfig and it finds the kernels and makes the menu.
It's a little more complex to set up but it does take care of getting the initrd together for raid+lvm, and it keeps previous kernels around with easy access in case they are needed to troubleshoot a problem. |
