Now the book is handling the case "/dev/shm is a link to /run/shm" correctly and

building LFS...

I have not tested completely, but what if we did this in LFS instead of a bind mount of $LFS/dev:

 mount -vt devtmpfs devtmpfs $LFS/dev

On my LFS system I then have:
 /mnt/lfs/dev/shm -> /run/shm

but if the host does not have  /mnt/lfs/dev/shm, then a simple
 mkdir -pv $LFS/dev/shm

should suffice.
