Hi all,
before I overwrite my MBR I want to test the new generated kernel on the my Debian host system (which uses grub as well). The Debian host system has the following EXT3 partitions: - /dev/hdb20: / - /dev/hdb23: /boot - /dev/hdb14: /mnt/lfs ... The new LFS partition is on /dev/hdb14 and /boot is a subdirectory. The part from /boot/grub/menu.lst where I boot the host system contains the lines =========================================================================== ... title Debian GNU/Linux, kernel 2.6.18-6-486 root (hd0,22) kernel /vmlinuz-2.6.18-6-486 root=/dev/hdb20 ro initrd /initrd.img-2.6.18-6-486 savedefault ... =========================================================================== I downloaded from www.kernel.org the 2.6.26.1 kernel and I did - make mrproper - make menuconfig - make - make modules_install - cp -v arch/i386/boot/bzImage /boot/vmlinuz-2.6.26.1 - cp -v .config /boot/config-2.6.26.1 - cp -v System.map /boot/System.map-2.6.26.1 I did the following trials 1.) I added the lines title LFS kernel 2.6.26.1 root (hd0,22) kernel /vmlinuz-2.6.26.1 root=/dev/hdb20 ro savedefault to /boot/grub/menu.lst This caused the following errors during boot VFS: cannot open root device "hdb20" or unknown block (0,0) Please append a correct "root=" boot option; here are the available partitions: Kernal panic - not syncing: VFS: Unable to mount rootfs on unknown - block (0,0) 2.) So I assumed that I need a initrd file and did a) cd /boot mkinitrd -o /boot/initrd-2.6.26.1 2.6.26.1 b) I added the lines title LFS kernel 2.6.26.1 root (hd0,22) kernel /vmlinuz-2.6.26.1 root=/dev/hdb20 ro initrd /initrd-2.6.26 savedefault to /boot/grub/menu.lst. This enabled a successful boot. However when I in the LFS chroot-environment I have no mkinitrd. How can I get it? Or is the problem that I have compiled the kernel with the following (EXT2 / EXT3) options: egrep '(EXT2|EXT3)' config-2.6.26.1 CONFIG_EXT2_FS=m CONFIG_EXT2_FS_XATTR=y CONFIG_EXT2_FS_POSIX_ACL=y CONFIG_EXT2_FS_SECURITY=y # CONFIG_EXT2_FS_XIP is not set CONFIG_EXT3_FS=m CONFIG_EXT3_FS_XATTR=y CONFIG_EXT3_FS_POSIX_ACL=y CONFIG_EXT3_FS_SECURITY=y Perhaps the problem is that EXT2 and EXT3 drivers should be in the kernel and compiled as modules, isn't it?
