LPIC-1 System Architecture Practice Question
During boot, the kernel must mount the root filesystem. Which of the following is responsible for providing the kernel with the location of the root filesystem?
⚠ Common exam trap
Candidates often confuse initramfs as the provider of the root filesystem location, when in fact initramfs is a tool that uses the location provided by the boot loader to mount the real root filesystem.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
boot loader
The boot loader (e.g., GRUB) is responsible for loading the kernel into memory and passing it the location of the root filesystem via kernel command-line parameters such as `root=`. Without this parameter, the kernel would not know which block device or partition to mount as `/`. The boot loader reads configuration files (e.g., `grub.cfg`) that specify this parameter, making it the direct provider of the root filesystem location.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
udev
Why it's wrong here
udev manages device nodes, not root filesystem location.
- ✗
initramfs
Why it's wrong here
initramfs is used to mount the real root, but it receives parameters from the boot loader.
- ✗
init
Why it's wrong here
init starts after the root filesystem is mounted.
- ✓
boot loader
Why this is correct
The boot loader passes root= parameter to the kernel.
