After updating some of our SLES 11 sp3 AWS instances to use the new infrastructure (per instructions in this blog post: our instances no longer retain their hostname. After rebooting, our systems hostnames are reset. For example, our test box was called "susetest" but after a reboot:

jfriesen@ip-10-16-31-137:~> hostname

Even though in "yast network" --> Network Card --> Hostname/DNS we ensure that the "Change Hostname via DHCP" checkbox is de-selected. Every time we reboot now, we lose our hostnames, and it seems like no settings in yast can fix the problem. This was not an issue before the infrastructure change. Anyone have any ideas?
