Curtin post installation question

[Syed Mushtaq]

Thanks for the reply Andres. I'm developing a MaaS plugin for Apache
Cloudstack. The idea is that MaaS will be a provisioner for baremetal
hosts. Now, in this Scenario, Cloudstack is incharge of networking. The way
I have it designed currently is that MaaS resides in a specific VLAN and
deploys the OS on the host. After the installation, I change the VLAN on
the ToR switch from Cloudstack (Cloudstack has plugins for ToR switches as
well), move it into the correct VLAN and move it to the the VLAN which
Cloudstack has designated for a particular virtual network. This way, both
VMs and Baremetal hosts can communicate.

Right now, I'm using preseed scripts to do most of the work like removing
the MaaS cloud provider because Cloudstack will now become the cloud-init
provider.

I have documented this in an FS at
https://cwiki.apache.org/confluence/display/CLOUDSTACK/MaaS+Integration+for+Baremetal+Provisioning+in+Cloudstack

I see your point that I should not manually trigger a deployed event before
the OS is installed. What I can do instead is to have some kind of
firstboot action which will do the required setup for me.

Does my approach make sense? Right now I am using preseed scripts to
acomplish running post-install commands. Is there any way I can achieve the
same using API calls?

I'm open to any and all suggestions. So please don't hesitate to tell me if
I am completely stupid and there is a better way to do things.

Thanks,
