#744 No /dev/shm device on compute nodes

[Jeremy Siadal]

The /dev/shm device is missing on compute nodes. We use
this device for various tests/runs in the HPC environment.

This device is added to the fstab file by default in a normal
installation. The oscarmaster script doesn't include this
option when it builds the fstab on compute nodes.

Since this is standard configuration for Red Hat head node
installs, and is sometimes needed for HPC applications, the
oscarmaster script should inlcude the following line during
the fstab creation:

none /dev/shm tmpfs defaults 0 0

This looke like an issue with SiSuite that Oscar uses to
generate images. Or rather, in trying to get this working,
we have found that sisuite does not have a good way to allow
for the mounting of /dev/shm. Email bsing sent to
sisuite-devel right away to figure out resolution.

Leaving ticket open until resolved in sisuite.
