From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Immutable distros aren't bad and can be a good thing. I just think it will take time before they are able to be troubleshooted by someone who may not be all that familiar with Linux.
Maybe I'm just hesitant to use something I don't understand. As far as updates go theoretically you shouldn't need to roll back if your testing is good enough. Reliability is why you use something stable and review each update before deploying. There needs to be a testing and validation pipeline for each update. Then again, that is not really possible for a one man team. In that case I would recommend setting up a generic image that spins up and creates a new machine id and keys before getting taken over by Ansible automation.
This is the kind of stuff that is used to admin thousands of VMs. Maybe it is simpler to use immutable distros but I haven't heard much from people who use them.
Overall I think I'll give them a shot in a VM. As for the user asking for help I'll just let them decide what's best for there needs.
If you have more than a handful of VMs Ansible is the answer
