Actually, just seen it myself, and I have:

% ls -ld /dev /dev/shm /run /run/shm
drwxr-xr-x 13 root root 3680 Jul 28 22:57 /dev
lrwxrwxrwx  1 root root    8 Jul 28 11:45 /dev/shm -> /run/shm
drwxr-xr-x 21 root root  840 Jul 28 22:57 /run
drwxrwxrwt  2 root root   40 Jul 28 11:45 /run/shm

So that's all set up correctly.  Unless my shell-fu is missing
something tonight, I'm not sure what's causing the mkdir to be
run here, given that the directory already exists.
