Re: Ubuntu instances + cloud-init
to my knowledge it is not distro specific. We are using that on Ubuntu 12.04 (Which is basically a Debian). We have just tried on a Debian 7.4 and that IF condition works.

Re: Ubuntu instances + cloud-init
Sure ;) On my Ubuntu 12.04 templates I use two scripts. One to change the root password, and the other to change the host name according to the one that was defined on CS. one is in "/etc/init.d/", and it is called cloud-set-guest-password. (The script is attached). and the second one is in "tc/dhcp/dhclient-exit-hooks.d/", so it is called right after the DHCP finishes its job. And its name is setHostName.

Hello, Those who are running Ubuntu instances, do you use cloud-init or the Cloudstack scripts? I'm trying to build some templates with 12.04 but can't find the right version of cloud-init for it (0.7.4); their "cloud images" comes with 0.6.3 who can't use Cloudstack as data source.
