[Bug 974584] Re: Semaphores cannot be created in lxc container

[Steve Langasek]

If it does make sense, the implementation that follows is:

if mountpoint -q /dev && mountpoint -q /dev/shm; then
  compat_link /dev/shm /run/shm
else
  [ -d /run/shm ] || mkdir -p /run/shm
  mountpoint -q /dev/ || compat_link /run/shm /dev/shm
fi

BTW, I realize there's another possible scenario, which is that /dev/shm
is a bind mount when /dev itself is not.  We should probably handle that
the same as if they both are (make /run/shm a symlink to /dev/shm), in
which case the first check just needs to be "if mountpoint -q /dev/shm".
