The particulars are that I've rebuilt a Fedora LiveOS filesystem image from a currently running instance (incorporating the filesystem changes in the device-mapper overlay into a new base filesystem image file).
Right, so essentially you're talking about chrooting into the LiveOS image temporarily. It's not really "halting" as such, just where the OS's idea of "root" is at the moment. That involves mounting your LiveOS filesystem as well.
The short answer is that if you can do it in the shell, you can do it in Python, but there's got to be more to the story than just this. What are you trying to actually do that you need Python for this? I assume you're trying to automate the process of what you're doing?
Almost probably this is possible with Python, if I understand what you're doing. If you just want to know how to write a Python script around the steps you want to accomplish, as a simple beginning Python experience, we may still be of service to you.
We could, for example point you to read up on the os.chroot() function in the Python standard library.
If your question has more to do with the particulars of managing chroot()ed mountpoints or preparing LiveOS images, you'd need to look to a forum devoted to that.
