Is it needed to reinstall custom kernel every time, after rebuilding?

Is it needed to reinstall custom kernel every time, after rebuilding?

[Amirali Shambayati]

Hi all,

Last time, I emailed to linux-kernel and kernenewbies mailing-lists
about how to speed up kernel compilation. I received very useful peace
of advice about using "ccache". Now I want to modify and compile a
unique custom kernel several times.
I used https://help.ubuntu.com/community/Kernel/Compile to compile
custom kernel. This tutorial uses "kpkg" command to build kernel and
it produces two .deb files: "linux-image" and "linux-header" as
result.
So for the first time I followed this tutorial.
For next times, according to to experts' advice, I use "make all" in
custom kernel root directory to rebuild kernel. I am not sure that it
would be enough to use changed kernel after rebooting. As I asked from
some experts, It is also required to install kernel again, but they
were not familiar with "kpkg" and "dbkg",... commands for kernel
installation.
Should I use "dbkg" command after every time I rebuild kernel, for
re-installation?
If anybody is familiar with these method of kernel installation,
please help me. It is very urgent, because it is related to my B.S.
thesis :P

Regards,

I decided, to first "make all" kernel package and using "dbkg" to
reinstall .deb files every time.
Could it be right?
(re-note: I want to build and install custom kernel for several times!)

I don't know about "dbkg" (i am not even sure such option exist, but I
do know there is "dpkg" and "rpm" as make target).

However, if you wanna be easy, why not do it manually? I mean, copying
the kernel image to /boot (along with creating initrd using mkinitrd
or specificly update-initramfs if you're using Ubuntu or its
derivatives) and edit the boot loader config (most likely you're using
GRUB 2 so the file is /boot/grub/grub.cfg.

Try to copy them into separate directories so you could easily
differentiate them.

could you please don't top post? :)

btw, IIRC "make all" also does kernel instalation and setting the boot
loader for you, so I see no point of doing make dpkg here

I am not really sure I really catch what you mean by "reinstall" :)

IMO reinstall is only a proper term when related to package
management. So, I think if you have to use the term "reinstall",
perhaps you confuse it with package management ? Sorry, maybe you're
under pressure but I can't help much with that.

If you build a new kernel and want to run that new kernel, then you must 
install that newly build kernel and reboot to it.
