Can LFS be copied from 1 hard drive to another after the build?

I have completed the LFS 6.0 book. System boots like a champ. I have started putting together things from BLFS. Still working smoothly. Before I go too much farther, I would like to know:

Can my current LFS be copied to another hard drive for future build considerations. I am only talking about the base LFS (no other packages installed). Currently, my LFS is on /dev/hda4. I would like to copy it to /dev/sda1 because I have a SCSI drive sitting there doing nothing. My host disto is on /dev/hda1 with /home on /dev/hda3. The swap partition for LFS and host is /dev/hda2.

What I am hoping to do is copy (not move) the root LFS to /dev/sda1, use /dev/sda2 for swap and /dev/sda3 for /home. I know I should have set my drive up with /dev/hda4, /dev/hda5, /dev/hda6 but I didn't realize the value of that when I started LFS.

Anyway, can it be copied?

Please also know that I understand that if it can be copied that the new /etc/fstab will have to be changed as well as /boot/grub/menu.lst, grub and recompiling the kernel (for scsi etc) all of which can be done from the host or the first LFS (using chroot) to be in the new environment. I just need to know what other considerations there are for this type of thing. My SCSI hard drive partition /dev/sda1 is larger than my /dev/hda4 so I am not concerned with running out of space. I am also not concerned with the time the computer may take in doing all of the copying. I just want to know if it can be done and what obstacles I may face.

Thanks.

Yes, I do this all the time, without problems, just make sure your copy method preserves file permissions and ownership and you should be in good shape.

Mad.

If I was you, I would try:

Code:

 => Boot host distro (assume sda1 has been formated)
# mount /dev/sda1 /mnt/sda1
# mount /dev/hda4 /mnt/lfs
# cd /mnt/lfs
# tar -c . | tar -xv -C /mnt/sda1
=> waiting for done :)

Just wanted to let you know that:
mount /dev/sda1 /mnt/sda1
mount /dev/hda4 /mnt/lfs
cd /mnt/lfs
tar -c . | tar -xpv -C /mnt/sda1

worked like a charm.

I added the "p" to preserve permissions on the extracted files. Everything is well so far.

Thanks
