What this mean? I have four partitions: Partition Mount Point Description sda1 / Initial OS, CentOS. sda2 swap Swap for the initial OS. sda3 swap Swap for LFS sda4 LFS Ext3 for LFS As a side note, having a separate swap partition for LFS isn't required, provided there is already a swap partition available on the host system. (See 2.2. Creating a New Partition for details): The swap partition for an LFS system can be the same as the one used by the host system, in which case it is not necessary to create another one. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Re: [lfs-support] Problems starting the final LFS system
Your fstab partitions are /dev/hda4 and /dev/hda3,
while in your grub - set root=(hd0,4) and root=/dev/sda4
I mean it should be either SDA or HDA,
SDA for SCSI drives while HDA for IDE drives
Correct drive names uniformly in /etc/fstab and /boot/grub/grub.cfg
depending on your hard drive type.

Yes, in grub.cfg you have root=/dev/sda4 (and the kernel boots, so it's
happy with /dev/sda) then the bootscripts choke because you
have /dev/hda in /etc/fstab.
sed -i 's#/dev/hda#/dev/sda#' /etc/fstab

When a boot fails, it's often best to concentrate on the first
error. From what you have shown, /run/var/bootlog: No such file or
directory. Do you have a tmpfs on /run in your /etc/fstab, and does
the /run directory exist ?
However, the more important message might have been before that!
Whenever a boot is failing in userspace, (i.e. no apparent kernel
failures), the best way to find the error(s) is to boot with
init=/bin/bash on the grub command line. That should give you a
read-only system for the root user. If you can get in to that, try
running the scripts from /etc/rcS.d/ in order. If you get those,
run the scripts from rc3,d/, again in order.
When you encounter an error, make a note of it - sometimes you can
fix it there, other times you will need to go back to chroot to fix
it. I assume that because you are using a virtual machine you will
also have other sessions available in which to read the book and
google for the problem(s) you encounter - that sounds a lot nicer
than bringing up a problematic boot on real hardware!
But either way, a pen and a stack of paper to note the errors will
probably come in useful.
If /bin/bash doesn't run because it is linked to libraries in
/tools, best to work out what went wrong (section 6.10, adjusting
the toolchain) and then make a fresh start ('start over' in
American). Most other erors are fixable.
If the earlier errors turn out to be a problem with the kernel
config, and it is releated to VirtualBox, you might find answers by
googling this list's archives - I know people have successfully
built LFS on it, and I know other people have misconfigured their
kernels.
Good luck!
