Not sure what category to put this under... anyway.

I have noticed for sometime now with 2.6 kernels on boot up /dev/shm
does not get mounted. This happened using devfs or udev. I didn't
really think to much about it since it didn't seem to impact anything. 

To make a long story short. I ended up in
/usr/src/linux-2.6.11-rc1/Documentation/filesystems/tmpfs.txt. The
paragraph of interest is;

2) glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
POSIX shared memory (shm_open, shm_unlink).
 Adding the following

   line to /etc/fstab should take care of this:

 tmpfs /dev/shm tmpfs defaults 0 0

   Remember to create the directory that you intend to mount tmpfs on  
if necessary (/dev/shm is automagically created if you use devfs).


Made the change and it now mounts.
