Jenkins and GNU/Linux OS Builds

[Christian Bryant]

I'm in the process of moving my Linux From Scratch build system to be 
managed by Jenkins (I can check up on the build using a Jenkins Android 
app).  However, I'm stumbling through examples of non-Java build 
configuration scripts that some folks have put out there for GCC and Linux 
kernel builds.  Anyone in the group built a build management framework for 
a GNU/Linux OS like Linux From Scratch?  From the Jenkins kernel build code 
below (not mine), I can see that I'm going to have a large number of shell 
tasks since I'm going to be building (on top of LFS 7.1) a large number 
(~200) of packages in addition to the kernel, and squirting out an ISO from 
this (for a Live DVD).  Appreciate any pointers from the local SMEs.  
Cheers.
