 |
|
Hi,
I have been working on a live CD and although I am progressing with runlevels, Xorg and the like, I always seem to have to specify the grub config file by hand. i.e. CD goes in, reboot, drops into grub shell, type: configfile=/boot/grub/menu.1st, liveCD boots up fine
The HOWTO I have followed is the one on gentoo-wiki:
http://gentoo-wiki.com/HOWTO_build_a_LiveCD_from_scratch
My current liveCD's grub configuration is (showing only first entry which is the one I'm booting - others are nofb and memtest)
/boot/grub/menu.1st
| Code: |
default 0
timeout 30
splashimage=(cd)/boot/grub/splash.xpm.gz
title=LiveCD genkernel
root (cd)
kernel (cd)/boot/kernel-genkernel-x86-2.6.14-gentoo-r5 vga=ask root=/dev/ram0 init=/linuxrc looptype=squashfs loop=/livecd.squashfs udev nodevfs cdroot dodmraid
initrd (cd)/boot/initramfs-genkernel-x86-2.6.14-gentoo-r5
|
The directory structure layout looks like this (as seen from outwith chroot)
| Code: | bluemell grub # pwd
/root/livecd/source/boot/grub
bluemell grub # ls -al
total 357
drwxr-xr-x 2 root root 544 Jan 17 22:36 .

Significant thing is no symlinking of menu.1st to grub.conf (the HOWTO says liveCD (or squashfs?) doesn't support booting symlinks)
At no point have I run the grub-install program (if I should, what is the grub root() device?)
Finally, here is the source's boot directory (from within chroot)
| Code: | bluemell boot # pwd
/boot
bluemell boot # ls -al

What do I need to do to get grub to pull up my grub config file menu.1st automatically?
Thanks

| Isn't the default file that it searches for menu.lst? (That's l as in llama). Ii think menu.1st is a typo or reading error. |

Excellent, we are good to go with the llama every time! I should have spotted that one, as it seems quite a common noob error to make with grub. Hmm. That's slightly embarassing that I made that mistake actually.
Thank you for spotting it!
