A Patch to Keep the Resizing of tmps Surviving Through Reboot

After a fresh installation of RHEL 6.1, I needed to adjust the size of tmpfs. However, I found it is a little more complicated than just add "size" option in /etc/fstab for tmpfs. The setting of "size" in /etc/fstab doesn't keep through system reboot. Then I found following patch against /etc/rc.d/rc.sysinit which can make it persistent:
