LOL I,m no expert it,s just that I got mine running with the same set up as you, yes build the kernel as in the book, Dont forget file system that resets and dont forget to copy the files over.
No dont use Ubuntu config file.
I know it takes time but you will learn things, It is trial and error with all this. I started the same as you I was helped with my problems.
Have a think about putting drive in laptop.
I have to go now I,ll be about tomorrow

have fun

I think I might have found an issue:

In section 6.43 we to configure grub install we use:

Code:
./configure --prefix=/usr
--sysconfdir=/etc
--disable-grub-emu-usb
--disable-efiemu
--disable-werror
We shouldn't be using --disable-grub-emu-usb, should we? If it is really the case, can I safely just recompile grub being at the final stage of LFS setup?

Fuck yeah, kurwa!!!

After 3 days (1 of which I spent configuring grub), I got this shit to work!

----

OK, here's how it goes: Grub boots from /boot partition so we need to set root=(hd0,1) which corresponds to /boot (/dev/sdb1 in my case) - sorry druuna, it's opposite of what you said. Now that we reside on boot partition temporarily, it is the root. So vmlinuz is /vmlinuz-3.1-lfs-7.0 rather than /boot/vmlinuz-3.1-lfs-7.0. As an argument to vmlinuz we need to supply true root of out system - in my case /dev/sdb4. So in my example my external disk is layed out as follows:
Code:
# Begin /etc/fstab

# file system  mount-point  type   options         dump  fsck
#                                                        order

/dev/sdb4      /            ext4   defaults        1     1
/dev/sdb2      swap         swap   pri=1           0     0
/dev/sdb1      /boot        ext4   defaults        0     0
/dev/sdb5      /home        ext4   defaults        0     0
proc           /proc        proc   defaults        0     0
sysfs          /sys         sysfs  defaults        0     0
devpts         /dev/pts     devpts gid=4,mode=620  0     0
tmpfs          /run         tmpfs  defaults        0     0
# End /etc/fstab
and proper way to configure grub.cfg assuming you are using one external usb hdd is:
Code:
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5

menuentry "GNU/Linux, Linux 3.1-lfs-7.0" {
insmod ext2
set root=(hd0,1)
linux /vmlinuz-3.1-lfs-7.0 root=/dev/sdb4 rootdelay=10 ro
}
btw. the trick that I saw in tutorial Druuna tutorial share - with using UUIDs in grub is not working for me. I get kernel panic when try to boot, so I assume it's unable to locate the root partition.

Well at this point I would really like to thank Druuna and Spiky, for pointing out a lot of things, that were really useful and eventually lead me to the right solution!
