Question 39

Why is the root file system mounted read-only during boot and remounted with write permission later on?

Because if problems with the root file system are detected during the boot, fsck can be run, without risk of damage.

Because this way crackers cannot collect information about root with boot sniffers.

To avoid writing to the disk, unless the root password is known.

To avoid other operating systems overwriting the Linux root partition.

Because the disk has its own write protection that cannot be changed by the operating system.

Question 40

In case the file containing the Linux kernel is lost, what happens when the system is booting?

The system starts normally since the bootloader copies the kernel to the master boot record of the hard disk.

Instead of the kernel, the initramfs is loaded and instructed to mount the root filesystem and reinstall the kernel from the original package or from source.

The bootloader mounts the root filesystem read-only and launches /bin/sh directly in order to allow the administrator to reinstall the kernel.

Without a kernel a system cannot boot and, depending on the bootloader, an error is displayed.
