`bin` file does not exist

[erayerdin]

Hello, I've been following A Minimal Rust Kernel tutorial. I am on Creating a Bootimage section. The problem is, even though build finishes successfully, .bin file does not exist. Here's build stdout:

WARNING: `CARGO_MANIFEST_DIR` env variable not set
Building kernel
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.07s
Building bootloader
    Finished `release` profile [optimized + debuginfo] target(s) in 0.07s
Created bootimage for `cernel` at `/var/home/erayerdin/Projects/cernel/target/x86_64-cernel/debug/bootimage-cernel.bin`

I do ls target/x86-64_cernel/debug/, which does not show any bin file at all.

Just in case if it is needed, here are some configurations:

# Cargo.toml
[package]
name = "cernel"
version = "0.1.0"
edition = "2024"

[dependencies]
bootloader = "0.9"

[profile.dev]
panic = "abort"

[profile.release]
panic = "abort"

[[bin]]
name = "cernel"
test = false
bench = false

# .cargo/config.toml

[unstable]
json-target-spec = true
build-std = ["core", "compiler_builtins"]
build-std-features = ["compiler-builtins-mem"]

[build]
target = "x86_64-cernel.json"
