some basic instructions on how to put it in place and I will get it working.
As for your request for comments/features, personally I would like to see the following
parts done initially:
I'm not sure of whether or not these things work in the status of these
things in fedora/RHEL. I suspect that all below is true other than
disk space resize. However, the following is true for ubuntu:
- hostname set to instance name
- hostname is set to whatever is in local-hostname of the metadata
service. I think that actually does correlate to 'name' in the nova
- disk space resize to flavor size
- cloud-init runs resize2fs on the root partition on start up. However,
if you have a partition table on the disk, right now, that relies upon
initramfs code delivered in cloud-initramfs-growroot  to grow the
partition , and tell the kernel to re-read the partition while the
filesystem is not mounted (otherwise you have to reboot).
- ssh-key pull
- cloud-init does that by default to the default user and adds it to the
root user's .ssh/authorized_keys, with a message that says "you need to
login as <the-configured-user>"
- report a random password for root user (or default user) if this is
- by default, cloud-init does not set a password for a user. However, it
can be told to via configuration (cloud-config in the image or passed
in via userdata). That looks like:
There is more info at .
Thanks for looking at this.

cloud-init on ubuntu does. Currently I have ssh keys getting imported but having some
problems getting the disk to dynamically resize to the flavor template as well as the

suggestions on how to get this done? Is there cloud-init for centos just like ubuntu? I
would also be interested in how to do this with debian as well.

It would help if you'd bring that up with upstream :)
I'm interested in cloud-init working in the most places it can. I'll try
to pull in the sysvinit scripts that Pádraig added and grab other changes
that are there.

If anyone has features / issues they'd like addressed in cloud-init,
please feel free to ping me (smoser). I'll most likely ask you to open a
bug at http://bugs.launchpad.net/cloud-init
, and may even invite you to
submit a patch. One way or another, though, I'm interested in making
cloud-init better, so comments/concerns/participation is welcome and
