Updating custom Ubuntu1004-STD images to fix control network discovery race condition

Currently, we do not have an elegant method to automatically update client scripts on custom Ubutnu images. This issue is important enough that you will want to update any Ubuntu images created before March 2, 2012. Two files need to be updated, dhclient-exit-hooks and findcnet. You should be able to copy and paste the commands below to easily update your image running on a testbed node. After that simply take a snapshot to update your image.

sudo curl --output /etc/dhcp3/dhclient-exit-hooks boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-dhclient-exit-hooks
sudo curl --output /usr/local/etc/emulab/findcnet boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-findcnet
sudo chmod a+rx /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet
sudo chown root:root /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet

Ubuntu804-STD

Ubuntu 8.04. We will continue to upate this image as long as it is supported by Ubuntu.
