I have just completed installing my LFS-6.5 (newly built) to a USB
drive. What follows is how I was successful to make a bootable LFS USB
drive..
I suggest you complete what Bruce suggests then:
Try this
1. prepare the USB drive by partitioning and formatting, I chose ext2
file system.
2. mount the USB drive, example: /mnt/usb
3. copy LFS from the hard drive to the USB drive
use a live CD or another install of linux, do not try to
copy the LFS system if you are running it as /dev/ will
give you trouble
rsync -var <source-LFS-location/*> <USB mount point>
or
cp -var <source-LFS-location/*> <USB mount point>
example:
rsync -var /mnt/lfs/* /mnt/usb
or
cp -var /mnt/lfs/* /mnt/usb
4. Install grub.
create menu.lst something like this and copy to /boot/grub/
# Config file for GRUB - The GNU GRand Unified Bootloader
# /boot/grub/menu.lst
timeout 5
default 0
color light-blue/black light-cyan/blue
title LFS 6.5 - USB
root (hd0,0)
kernel /boot/lfskernel-2.6.30.2
root=/dev/disk/by-uuid/03e82132-a199-4601-a20e-106c444a2c5a ro quite
# EOF
The root (hd0,0) is correct, the USB drive will be hd0,0 at boot (you
may have to change the last 0) if you copied LFS to a partition other
than 1 (the first)
The kernel line should use the disk-by uuid...keeps one sane :)
to find the uuid
type at a CLI (terminal) blkid /dev/sdx - where sdx is the USB device
example from my "install":
blkid /dev/sdd1
/dev/sdd1: UUID="03e82132-a199-4601-a20e-106c444a2c5a" TYPE="ext2"
Now at a root CLI prompt
grub
root (hdx,x)
setup (hdx)
The root line will vary according to the USB device is /dev/sdd1 is root
(hd3,0), setup (hd3)
5. Fixup /etc/fstab
example:
# Begin /etc/fstab
# file system mount-point type options dump fsck
#
order
/dev/disk/by-uuid/03e82132-a199-4601-a20e-106c444a2c5a / ext2 defaults 1
1
#/dev/xxx swap swap pri=1 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 /dev/shm tmpfs defaults
0 0
# End /etc/fstab
Again use disk/by-uuid with the uuid from the previous step
Reboot to the USB drive.
