Poke around and find out
There is a particular kind of confidence that comes just before things go wrong. It is a confidence like that of someone eager to skip to the interesting part, without reading what comes before.
I tried installing Omarchy inside a Distrobox container. Seemed reasonable enough, or at least I had not done enough digging to know it was not. The installer reached outside the container and overwrote home directory configuration files, messing up my Bluefin install. The fun stuff layered on top by default, especially the dinosaurs in my terminal, was gone.
The funny thing is that my system was fine. Bluefin is immutable. Nothing was actually broken. I removed these new configuration files and recovered my old ones. Despite that, I reinstalled anyway, just because the feeling of not trusting my own machine was worse than the hour it took to start clean.
Sometimes the damage is not to the system. It is to your confidence in it.
