Thanks Johnny,
I recently found that it write some scripts in /etc/rc.local which change root password to a random password and lock it.
In addition, I found it created an centos account at first boot.
I think there may other changes here, so where can I find these *source code*?
Thanks anyone in advance!

Hi list,
I found centos genericcloud image for openstack at https://docs.openstack.org/image-guide/obtain-images.html#centos
but I didn't found any release note for these images, so I didn't known what's difference between genericcloud image and the official centos release, e.g. centos 6.8, 7.2 release and etc.
Is there any wiki/doc/releasenote?
There is no real difference, the Generic Images are a point time image made from CentOS (either 6 or 7) for the end of the month for that date. For example, CentOS-7-x86_64-GenericCloud-1705.qcow2c is an image created with the latest packages from the end of May 2017, and is represented as 1705 (YYMM).
It is basically a minimal install (plus the cloud-init RPM and it's dependencies) that you can add things to with 'yum install' and it includes the base OS and the updates from May 31, 2017. We do one every month. It works just like a minimal install of CentOS if you did it from the installation ISOs. Here is a link:
http://cloud.centos.org/centos/7/images/
We also have vagrant box installs and atomic installs if you need those instead of VM images:
http://cloud.centos.org/centos/7/atomic/images/
http://cloud.centos.org/centos/7/vagrant/x86_64/images/
All of these images are just a different way to get base CentOS plus updates for the end of a given month.
We also create an ISO set for the same date here, if you prefer ISO installs to images:
https://buildlogs.centos.org/rolling/7/isos/x86_64/
Those are also point in time (end of the month) ISO sets that are base CentOS plus all updates at the time they are generated.
