Which technique is used in modern kernels to reduce their disk footprint?
Kernel images are compressed to reduce diskspace.
What is the purpose of using kernel modules?
In order to only use resources when needed, kernel modules can be loaded into the kernel on demand. Also, modules can be changed and reloaded without the need to reboot the kernel.
Why is running the command make mrproper generally a good idea?
As it prevents problems with the subsequent configuration and/or build of the kernel.
What is the most important advantage of running make config in stead of make menuconfig, make xconfig or make gconfig?
The command does not depend on any full-screen display capabilities and is therefore useable on slow links and systems with limited display capabilities.
What needs to be done after running make modules?
make modules_install is used after
succesfully building the modules (device drivers and other
items that were configured as modules). This installs them
For which distributions should you use mkinitramfs for creating an initrd image?
The debian(-based) distributions use mkinitramfs.
By which means can a patch be removed from a production kernel?
Either apply the patch again or run the command patch with the -R parameter.
Why is using modprobe recommended instead of using insmod to insert modules?
Modprobe is more specific about errors. It also works with just the module name and it can handle prerequisite relationships between modules.
By which means may the version of the running kernel be determined?
You could check by usingcat /proc/sys/kernel/osrelease or by using uname -r.
Which command generates the file
This file is generated by the depmod command.
Which technique is used in modern kernels to reduce their memory footprint?
On demand loadable modules are used to reduce a kernel's memory footprint.
For which reason was udev designed?
It was designed to make Linux device handling more flexible by taking device handling out of the kernel into user space.
