I actually have enough spares. Can clone and try it, why not? It's a nice idea
The customization I did should not be breaking. I've installed some packages, written some small tools, added some cron jobs, maybe changed some services' default parameters, etc. I actually use Debian for ~13 years now, and Linux in general for a bit longer. So I'm used to do small changes in my systems as I use them and find places which can be tuned better for my requirements. Since they're too small & short to document, they generally got lost in the process. This is why I'm hesitant to take the risk
Thanks again for the quick reply. I'll keep the progress updated in this thread.
