3258	Mounting /dev/shm can break some hosts	Matthew Burgess	bdubbs@…	"As reported at http://www.linuxfromscratch.org/pipermail/lfs-dev/2012-December/067476.html the instructions to work around the fact that some hosts have symlinked /dev/shm to /run/shm can in fact break those hosts.  Once the /dev/shm symlink is removed from the host, it's never recreated!

The fix from Pierre, in that thread, looks good:

{{{
if [ -h $LFS/dev/shm ]; then
   mkdir -p $LFS/run/shm
   mount -vt tmpfs shm $LFS/run/shm
fi
}}}

So, we mount the shm FS into the target of the symlink, rather than removing the symlink.

We'll need to add an errata item for this as well."	defect	closed	normal	7.3	Book	SVN	normal	fixed
