The required contents of fstab changed a few days ago. The documentation is in the process of being updated.

Add the following line to your /etc/fstab:

    devtmpfs /dev devtmpfs mode=0755,nosuid 0 0

i have just ran into this exact same problem, adding that line has not fixed it, i just get the error unknown filesystem type devtmpfs

i just found this in the kernel configuration, im just enabling and recompiling my kernel to see how it goes

Device Drivers --->
  Generic Driver Options --->
     Maintain a devtmpfs filesystem to mount at / dev

Yes, you also need devtmpfs support in your kernel. Again, this requirement has only been added to LFS recently.

I'll be sure to add this info to the documentation.
