Question 96 of 522
Quick Answer
The answer is /bin. This directory holds essential user command binaries like ls, cp, and mv that must be available even when only the root filesystem is mounted, which is precisely the condition during single-user mode and early boot stages. According to the Filesystem Hierarchy Standard (FHS), /bin contains the core utilities needed by both administrators and users for system repair and recovery when no other filesystems are accessible. On the LPIC-1 exam, this concept tests your understanding of the FHS structure and the critical distinction between /bin and /usr/bin, where /usr/bin may not be mounted in single-user mode. A common trap is confusing /sbin with /bin—remember that /sbin holds system administration binaries for root, while /bin serves all users. For a quick memory tip: think of /bin as the "bare essentials" bin—the commands you cannot boot without.
LPIC-1 Devices, Filesystems and FHS Practice Question
This LPIC-1 practice question tests your understanding of devices, filesystems and fhs. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which directory in the Filesystem Hierarchy Standard (FHS) contains essential user command binaries that are needed in single-user mode?
Answer choices
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
✓
/bin
The /bin directory contains essential user command binaries (e.g., ls, cp, mv) that are required for system booting and repair in single-user mode. According to the FHS, /bin is intended for commands needed by both the system administrator and users when no other filesystems are mounted, making it critical for single-user mode operations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse /sbin with /bin, assuming that system administration binaries are the essential ones for single-user mode, when in fact /bin provides the user-level commands needed for basic system interaction and recovery.
Detailed technical explanation
How to think about this question
In single-user mode, only the root filesystem is mounted, and /bin must be self-contained on that partition to provide core utilities like sh, mount, and fsck. The FHS mandates that /bin be available before /usr is mounted, which is why modern distributions often symlink /bin to /usr/bin, but the standard still requires the essential binaries to be accessible via /bin. A real-world scenario is recovering a system with a broken /usr mount, where /bin commands are the only tools available to repair the system.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the LPIC-1 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
