[ale] compiling kernel with version modifier

[Todor Fassl]

I am compiling a kernel now after having run "make menuconfig" and 
changing the local version. For the archives, I'll post a message with 
the results after it's done. I've already made some progress though. I 
got the string to show up in "uname -a". I edited the line in 
debian.master/changelog and added +spk to the version number. When I 
installed that kernel, it said it was installing over the current stock 
ubuntu kernel (which is good). "uname -r" was unchanged. However, "uname 
-a" did show that I was using my own kernel:

$ uname -a
Linux vv507k 4.2.0-30-generic #36+spk SMP Wed Mar 2 16:18:22 CST 2016

x86_64 x86_64 x86_64 GNU/Linux

I am thinking that if I follow your advice, I'l end up with a kernel 
where "uname -r" yields "4.2.0-30-generic-spk" which would be perfect.
Thanks to you and the others who replied for your help.
