Ask HN: Arch Users – What is your long-term system maintenance routine?

Hi Community, been a happy Arch Linux user for many years, keeping up with minimal system maintenance and occasionally performing some package cleanups (using commands like pacman -Qtd).

I'm curious about your long-term system maintenance routines. What steps do you take to ensure your system stays stable and up-to-date, and how long have you managed to keep your system running smoothly without needing to reinstall?

Thanks for your insights!
