After manually compiling and installing a new kernel, what has to be done regarding the initramfs?

• 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 automatically. The new initramfs only needs to be installed
• D. The system should be restarted since the initramfs reconfigures itself for the new kernel during the startup of the system

• B. Apply the patch file to the kernel source directory containing kernel version 4.6.0
• C. Apply the patch file to the kernel source directory containing kernel version 4.6.3
• D. Uncompress the file using xz to get the uncompressed patch file
• E. Use patch to apply the uncompressed patch file to the source directory of any previous kernel version

What is the purpose of an initramfs during the Linux system start?

• 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

• C. sync
• D. systemctl emergency
• E. systemctl reboot

• B. grub-mkconfig
• C. grub-install-mbr
• D. grub-glue-mbr
• E. grub-mbr-setup

What effect does the f option to the update-rc.d command have on files in the /etc/rcX.d/ and
/etc/init.d/ directories?

• A. It will force the removal of the symlinks in /etc/rcX.d/ even when the links are read only
• B. It will remove both the symlinks in /etc/rcX.d/ and the init script in /etc/init.d/
• C. It will remove the init script in /etc/init.d/ and the symlinks in /etc/rcX.d/ and update the package information of installed files
• D. It will force the removal of symlinks in /etc/rcX.d/ even if the corresponding init script still exists in /etc/init.d/

Fill in the blank:
What command ensures that the file systems are written to disk after a lot of write operations?
(Specify ONLY the command without any path or parameters.)

What is the purpose of a system mount unit?

• A. It is used by the command systemd-mount and allows users to mount partitions to mount points of their choice
• B. It is used only to mount network file systems to local mount points. It cannot be used for local media
• C. It is created by the command systemd-fstab-generator to integrate entries from /etc/fstab into the system boot process
