* `-Zmiri-seed=<hex>` is a custom `-Z` flag added by Miri. It configures the
seed of the RNG that Miri uses to resolve non-determinism. This RNG is used
- to pick base addresses for allocations, and when the interpreted program
- requests system entropy. The default seed is 0.

+ this is also used to emulate system entropy. The default seed is 0.
**NOTE**: This entropy is not good enough for cryptographic use! Do not
generate secret keys in Miri or perform other kinds of cryptographic
operations that rely on proper random numbers.
useful for debugging. It means Miri will miss bugs in your program. However,
this can also help to make Miri run faster.
* `-Zmiri-disable-isolation` disables host host isolation. As a consequence,
- the program has access to host resources such as environment variables and
- randomness (and, eventually, file systems and more).

* `-Zmiri-ignore-leaks` disables the memory leak checker.
* `-Zmiri-env-exclude=<var>` keeps the `var` environment variable isolated from
the host. Can be used multiple times to exclude several variables. The `TERM`
