I downloaded the kernel from the kernel.ubuntu.com repository and I am playing with it.

The kernel can be compiled using make oldconfig, make all and make modules_install. Then the kernel image can be copied to the /boot folder and the modules to the /lib.

So, why there is an another way to do it using debian/rules?

Doesnt it make it more complicated?

My second question is that I ran make mrproper and the directory debian was automatically deleted. How can I restore the debian directory again because all the rules pertaining to the compilation are stored there.

  • You can just copy files and such as you mention. However in doing so you are by-passing package management, dpkg at the primitive level, apt or apt-get at the next level. The suggestion is that this is undesirable. I do not believe that using the debian/rules method is new, but rather just a different method resulting in proper .deb file install-able as packages. While it might be considered more complicated, it is also considered more within the Ubuntu package management environment. – Doug Smythies Mar 22 '17 at 15:43
  • I do not know the answer to your last question. Why not? Because I have never had much success compiling the kernel that way. I only use this method. – Doug Smythies Mar 22 '17 at 15:44
  • Sounds good. Then I would stick with the packet management instead of copying manually. – infoclogged Mar 22 '17 at 16:32
