Question 420 of 527
LPIC-1 System Architecture Practice Question
To add a kernel parameter temporarily to the kernel command line at boot, what key should be pressed in the GRUB menu?
⚠ Common exam trap
Candidates often confuse the 'e' (edit) key with 'c' (command line) or 'b' (boot), assuming they can add parameters via the GRUB shell or by simply booting, but only 'e' provides direct access to modify the kernel command line for a single boot.

Correct answer & explanation
✓
e
Pressing 'e' in the GRUB menu enters the edit mode for the selected boot entry, allowing you to temporarily modify kernel parameters on the command line (e.g., adding 'single' for single-user mode or 'nomodeset' for graphics issues). These changes apply only to the current boot and are not saved to the GRUB configuration file.
