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

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

D. To avoid other operating systems overwriting the Linux root partition.

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

A. To initramfs is independent of the kernel and should not be modified unless the hardware configuration of the machine has changed

B. Since the initramfs contains kernel modules, a new initramfs must be built for the new kernel

C. During the compilation of the Linux kernel, a new initramfs is built automaticall

D. The new initramfs only needs to be installed

E. The system should be restarted since the initramfs reconfigures itself for the new kernel during the startup of the system

A. /init

B. /initrd

C. /linuxrc

D. /rc.local

E. /sbin/init

A. It loads required modules and starts sub sytems like LVM to make the root file system accessible to the kernel

B. It moves the kernel from normal system memory to initram memory to speed up kernel access

C. It copies the root file system’s content to RAM to speed up the system and reduce writes to disk

D. It creates a ram disk to store volatile data for directories like /tmp to reduce writes to disk
