Design a disk that boots in UEFI mode.
Provide an area from which firmware can load EFI applications such as a bootloader.
Which partition is required?
The EFI System Partition is normally FAT-formatted and stores UEFI bootloaders and other EFI applications.
Detailed explanation
Incorrect. tmpfs is a temporary filesystem, not the firmware boot partition.
Incorrect. swap is a memory backing area.
Incorrect. An LVM physical volume alone is not the UEFI firmware partition.
Correct. The ESP provides the firmware-readable EFI application storage.
Try it yourself
An example you can run in a temporary verification environment.
lsblk -o NAME,FSTYPE,PARTTYPENAME,MOUNTPOINTS 2>/dev/null | headExpected result
ブロックデバイス情報。UEFI環境ではEFI System等が見える場合があるKey points
- ESP is for UEFI
- It is normally FAT-formatted
- It may be mounted at /boot/efi
Notes
- Environment: Linux / UEFI・util-linux lsblk
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
Foundation review
Read the scope first
Check whether the command acts on the current shell, a new process, an existing process, or a file.
Verify the observable result
Use the supplied command and compare the output with the expected result.
