Interesting, one of the last SL6 VMs we have doesn't do this.

The "sandbox" init script (/etc/init.d/sandbox) has mount commands that setup bind mounts for /tmp etc. The comments in the script say:

# description: sandbox, xguest and other apps that want to use pam_namespace \
#              require this script be run at boot.  This service script does \
#              not actually run any service but sets up: \
#              /var/tmp, /tmp and home directories to be used by these tools.\
#              If you do not use sandbox, xguest or pam_namespace you can turn \
#              this service off.\
#

No idea if this is related.
