The Rust code using `.unwrap()` is explicitly testing for a missing value and signaling a well-defined error when the prerequisites are not met. Contrast this with dereferencing a null pointer in C, where doing so results in undefined behav

That would be an issue if you only had crypto. It does not in any way negate the fact that there are ways to employ crypto profitably which do not require exposing your real-world identity.

You can wait until just before the next time the device is scanned for filesystems, or perhaps when the next btrfs filesystem is mounted. Beyond that it will start to cause problems.

The difference is that you can easily edit the UUID of a btrfs filesystem with `btrfstune -U` immediately after making the copy so the filesystems are unique again. You need to do this anyway if you have mount rules based on the UUID, regar
