LILO issues...


I installed Gentoo from stage1 today. Never tried Gentoo, but I always hear good stuff about it. After completing the install, I didn't install LILO, as I already have it installed to the MBR. I just booted to Slack, edited lilo.conf, then ran /sbin/lilo and I keep getting this error:

root@dabasement:/home/scruff# /sbin/lilo
Added Slackware *
Fatal: open /boot/kernel-2.4.20-gentoo-r8: No such file or directory

I know kernel-2.4.20-gentoo-r8 is there. Did mkdir /dev/hda6 /gentoo : ls /gentoo/boot and it's in there. I tried /sbin/lilo while hda6 was mounted and not mounted. Here is disk setup:

hda1 winXP 20gb's-- primary
hda3 / Slackware 13gb's-- primary
hda4 /home (slack) 13gb's-- primary
hda5 swap 512mb's-- logical
hda6 / Gentoo 8gb's-- logical
hda7 /data (vfat) 80gb's-- logical

Here is my lilo.conf:

boot = /dev/hda

prompt

vga = 791

image = /boot/vmlinuz
root = /dev/hda3
label = Slackware
read-only # Non-UMSDOS filesystems should be mounted read-only for checking

image = /boot/kernel-2.4.20-gentoo-r8
label = gentoo
root = /dev/hda6
initrd = /boot/initrd-2.4.20-gentoo-r8
read-only # Non-UMSDOS filesystems should be mounted read-only for checking

other = /dev/hda1
label = WinXP
table = /dev/hda

I also tried like the install manual shows with the 'append="root.......etc" ' but it didn't help. What simple little detail am I missing?

you say /gentoo/boot is on /dev/hda6, but in lilo.conf you try to load /boot/kernel-2.4.20-gentoo-r8 on /dev/hda6.
lilo just can't find the /gentoo dir IMO.
Structure on the /dev/hda6 partition should be /boot, not /gentoo/boot, no?

It isn't /gentoo/boot. I just created that dir in slack so I could view the contents of /boot on the gentoo partition. I had this problem before I did that though. After it wouldnt work, I did mkdir /gentoo mount /dev/hda6 /gentoo just so I could list the contents and be sure I was using the correct kernel name. I didn't add it to fstab or anything like that.

There are two or three ways to go about this:
  1. Copy the gentoo kernel and initrd from /gentoo/boot the slackware /boot directory. NOTE: It's not enough to just mount the gento directory because lilo is looking in the slack /boot directory:
    cp /gentoo/boot/kernel-2.4.20-gentoo-r8 /boot
    cp /gentoo/boot/initrd-2.4.20-gentoo-r8 /boot
  2. Change the /etc/lilo.conf entry like this:
    image = /gentoo/boot/kernel-2.4.20-gentoo-r8
    label = gentoo
    root = /dev/hda6
    initrd = /gentoo/boot/initrd-2.4.20-gentoo-r8
    read-only
    NOTE: This way is better than above but you always need to have gentoo mounted at /gento before running lilo.
  3. First fdisk /dev/hda and make /dev/hda6 bootable. Next do a chroot /gentoo and make sure the gentoo /etc/lilo.conf is like this:
    boot = /dev/hda6
    prompt
    vga = 791
    image = /boot/kernel-2.4.20-gentoo-r8
    label = gentoo
    root = /dev/hda6
    initrd = /boot/initrd-2.4.20-gentoo-r8
    read-only

    Then run lilo from gentoo.
    NOTE: This will put lilo on the /dev/hda6 boot partition.

    Now you can exit the chroot and you are back to slackware. You need to change slackware lilo.conf like this:

    other = /dev/hda6
    label = Gentoo
    table = /dev/hda

    And run lilo again in slackware.

I'm sure there are other ways to do it also.

<edit> Also rather than doing chroot /gentoo you could just edit /gentoo/etc/lilo.conf and when you run lilo do it like this:

lilo -r /gentoo

Damn. I figured your suggestions would DEFINITELY fix me up, but I still get the same error. I tried the #1 suggestion first, nope. HOW the hell can lilo NOT find kernel--- when it's located in the same directory as my slack kernel?! Of course, I edited and saved lilo.conf first, to look for the kernel at /boot/kernel----.

Then, I tried the 2nd suggestion (which I think I already tried while hacking away at it) and it didn't work either. Why won't lilo recognise the image??

root@dabasement:/home/scruff# ls /gentoo/boot/
. .keep System.map-2.4.20-gentoo-r8 initrd-2.4.20-gentoo-r8
.. System.map boot kernel-2.4.20-gentoo-r8

As for #3, I don't even a lilo.conf in gentoo right now (never emerged it), and am a little leary of installing it from there. The reason being, is right now from slack (completely configured as I need it) I can't get lilo to boot gentoo, so whats to say from gentoo I wont be able to get slack to boot? I have the slack live cd, knoppix, and all that, but I don't want to create any more problems than I already have

Try ls -l /gentoo/boot

And post the results.

Simply, create a mount point in Slackware for the Gentoo partition which contains Gentoo's kernel - then mount the partition into the mountpoint in Slackware - once youve done this then put an entry for Gentoo in lilo.conf (while inside Slackware) - make sure you take into account the temporary mounted nature of the Gentoo partition inside Slack:

With a mount point of /mnt/gentoo :

image=/mnt/gentoo/boot/kernel-2.4.20-gentoo-r8
label="Gentoo"
root=/dev/hda6
initrd = /mnt/gentoo/boot/initrd-2.4.20-gentoo-r8
read-only

then save lilo.conf

then type

/sbin/lilo

to re-install the bootloader and new map file..

Thats #2 in my post.

Your lilo.conf in slackware looks like this?
image = /gentoo/boot/kernel-2.4.20-gentoo-r8
label = gentoo
root = /dev/hda6
initrd = /gentoo/boot/initrd-2.4.20-gentoo-r8
read-only

It did. I just copy/pasted Skyline's text into lilo.conf and /sbin/lilo passed. The only thing I did differently was mount /dev/hda6 @ /mnt/gentoo. I suppose it's possible I had a typo, but I have been fooling with this for 2 hours and typed the gentoo entry over 20x during that time. Hard to believe I had a typo each time, especially when I checked each entry over hardcore each time.

Also, the entry you saw above that I posted was copy/pasted directly from lilo.conf...

Let me reboot and see what happens...

Maybe it was the spaces, I just copied your lilo.conf and made changes and I left the spaces there but my lilo.conf doesn't have any spaces.

Anyway glad to hear it is working.

Yep, thanks guys! Now I have new problems to solve, lol. Getting some kernel errors, haven't got X configured properly yet (have to use ps2 adapter for mouse) and don't have internet yet, WHEEEEE!!!! I'll get it worked out though. I got so used to Slack, I'll have to learn some new stuff for Gentoo. At least I can copy most of my settings for stuff like internet from slack. Going to try using my Slack kernel. It's custom and works perfect on my hardware.

Thanks again!
