A humble piece of advice from a fellow system admin... Never ever build a system that "you cannot simply reinstall." There should be at least two ways to redo everything: 1. From scratch using documentation or preferably a modern deployment system such as Ansible, Salt, etc. 2. From backup. This should be drilled from time to time, even without a practical need, just to make sure things work as expected. Yes, practice is not as simple as theory and I admit being guilty at times of every possible mistake in not following the above. :-] But, realistically speaking, as long as a system still functions, it should be reproducible. Document the setup, backup its configs and saved data, etc.
