 Posted: Sun Sep 16, 2012 6:14 pm Post subject: Grub2 and Custom Kernel Parameters |
 |
|
Hello,
My Gentoo install has the root partition on an dm-crypt'ed LVM2 volume. The kernel is built using genkernel which takes care of installing the relevant files into /boot and building a suitable initramfs. However, a consequence of this is that my /boot/grub2/grub.cfg file has lines such as:
| Code: |
menuentry 'Gentoo GNU/Linux, with Linux x86_64-3.4.4-gentoo' --class gentoo --class gnu-linux --class gnu --class os {
load_video
insmod part_gpt
insmod ext2
set root='(hd0,gpt2)'
echo 'Loading Linux x86_64-3.4.4-gentoo ...'
linux /kernel-genkernel-x86_64-3.4.4-gentoo init=/linuxrc dolvm crypt_root=/dev/sda3 root=/dev/ram0 real_root=/dev/mapper/main-root ro
echo 'Loading initial ramdisk ...'
initrd /initramfs-genkernel-x86_64-3.4.4-gentoo
}
|
Notice the extra parameters to the kernel (init, dolvm, crypt_root and real_root). The funky grub2-autogenerate-config-files-through-inspecting /boot is oblivious to these parameters. Hence, I am force to manually maintain the grub config file myself. How can I inform grub2 that extra parameters are required?
Regards, Freddie. |
