Grub install LFS 5.x


Buenos Dias!

This may be a stupid question but say I already have grub installed from say my other distros, should i still install it during the LFS installs? Also, should I mount my /boot partition during the installation of LFS since this is what I always boot from? It is a dedicated 200 MB partion on sda. Sda also houses Fedora1. LFS is sdd1 My data is sde1. sdb and sdc are other distro's.

Thanks,

I would add my LFS kernel to your existing /boot partition and add an entry to your existing grub.conf to boot it. There is no need to reinstall grub. You can also set up your LFS fstab to mount your shared /boot partition when booting LFS but it is not necessary.

Ok.... I skip the installation of Grub in CH6 on LFS 5.1.1. I was going to use my /boot partition that already existed from my FC1 installation. In my chroot environment I mounted /boot. The only other deviation was the below.


During kernel installation
Line read:
cp arch/i386/boot/bzImage /boot/lfskernel
Changed to :
cp arch/i386/boot/bzImage /boot/lfskernel-2.4.26
AND..
Line Read:
cp System.map /boot
Changed to:
cp System.map-2.4.26 /boot

I also copied the .config file in the same manner. I saw some documentation on the net that said this was the best way to keep all your kernel versions straight.

Now, when I boot to LFS I get ,"ERROR 15 File not found", This seems to be a stage 2 error, but I don't know what file it can't find. I checked all my syntax and it all is seems to be correct. no typos as far as I can tell. Also I can boot fine to whatever FC kernel version I want. So I googled!!!!

Can't seem to find the answer. It will be good to note:
/dev/sda1=/boot
/dev/sda3=/ for FC1
/dev/sdb1=/ for LFS
/dev/sdc1= /data
Also, I created /dev/sdb1 after my FC1 install using cfdisk. I am using ext3 which is compiled into the kernel.

Here is my Grub.conf which is also the same as menu.lst.

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2197.nptl)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2197.nptl ro root=LABEL=/ rhgb
initrd /initrd-2.4.22-1.2197.nptl.img
title Fedora Core (2.4.22-1.2197.nptlsmp)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2197.nptlsmp ro root=LABEL=/ rhgb
initrd /initrd-2.4.22-1.2197.nptlsmp.img
title Linux From Scratch 5.1.1 (2.4.26)
root (hd1,0)
kernel --no-mem-option /boot/lfskernel-2.4.26 root=/dev/sdb1
title Fedora Core (2.4.22-1.2194.nptlsmp)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2194.nptlsmp ro root=LABEL=/ rhgb
initrd /initrd-2.4.22-1.2194.nptlsmp.img

Can anyone help? Let me know if you need more info!

Code:
title Linux From Scratch 5.1.1 (2.4.26)
root (hd1,0)
kernel --no-mem-option /boot/lfskernel-2.4.26 root=/dev/sdb1
you want to change root (hd1,0) to (hd0,0)

root tells grub where you keep your kernels, and it is with the rest of them on sda1, or in grub terminology (hd0,0)

That fixed it along with removing /boot in the kernel line!

Thanks,
