 It sounds as if /dev is not getting mounted.  Among the
requirements for that are:

chapter 6 : udev correctly installed

kernel config :
 I also have
 but that option might not have existed in the old kernel used for
LFS-7.1, and indeed might not be required.  It certainly does no

 I remember having problems around LFS-6.8 when I upgraded my server
and carried over CONFIG_SYSFS_DEPRECATED : if you set that, try
turning it off.

/etc/fstab : the line for /dev -
devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0

directories : /dev mount point exists (I guess that was correct,
otherwise the bind mount of the host's /dev to /mnt/lfs/dev would
have failed).

 A last thought : if you didn't build the correct disk drivers
*into* the kernel (NOT as modules), that can also cause this sort
of problem.  This is where the a Live CD can be useful: they build
everything as modules, using an initrd, so 'lsmod' will tell you
which modules were actually installed for your hardware.

das eine Mal als Tragödie, das andere Mal als Farce
