How do I change/edit kernel name (the one in uname -r)?

Question

I tried to change kernel version name of Raspbian using the steps in http://goterminal.blogspot.com/2012/02/make-kernel-name-same-as-your-name_07.html meant for Ubuntu.

For example I want to change the kernel version name from 4.4.30-7+ to 4.4.30-7+-Afif-Custom

The steps are stated like this:

1. sudo apt-get install kernel-wedge kernel-package libncurses5-dev
2. sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
3. mkdir ~/src
4. cd ~/src
5. sudo apt-get source linux-image-$(uname -r)
6. cd linux-2.6.38 (__I presume a different directory name will appear there__)
7. make menuconfig
8. export CONCURRENCY_LEVEL=3
   • Concurrency_level = 2 ( Number of processor cores) + 1
9. make-kpkg clean
10. time fakeroot make-kpkg --initrd --append-to-version=-tweak kernel-image kernel-headers
11. cd ~/src
12. sudo dpkg -i linux-image-2.6.38.2-tweak_2.6.38.2-tweak-10.00.Custom_i386.deb
13. sudo dpkg -i linux-headers-2.6.38.2-tweak_2.6.38.2-tweak-10.00.Custom_i386.deb
14. sudo reboot (or) sudo init 6
15. uname -r

I'm stumped for days at step 2. The linux-image-$(uname -r) part doesn't work for me. I'm currently using Raspbian kernel version 4.4.30-v7+. Even when I use 4.4.27-7+ the linux-image-$(uname -r) part won't work too... It says the version does not exist.
