What does the bootloader typically do next?

Hint 1: Focus on the requirement

Identify the bootloader work that prepares the kernel handoff.

Hint 2: Key terms

Correct選択されたカーネルとinitramfsをメモリへ読み込み、カーネルへ制御を渡す

Correct. The bootloader loads the kernel and initramfs and transfers control.

Incorrectコンテナイメージをregistryへ送信する

Incorrect. Sending images to a registry is a container operation.

An example you can run in a temporary verification environment.

cat /proc/cmdline

現在kernelへ渡されたcommand line

Environment: 実行中Linuxの読み取り専用情報
Use read-only commands or a disposable Linux instance when checking boot metadata.
Exact unit names and command output can vary slightly by distribution.

Foundation review

A bootloader combines the selected kernel, initramfs, and parameters before transferring control to the kernel.

Read /proc/cmdline to inspect parameters already passed to the running kernel.
