LTS Enablement Stack

Jorge Castro had a good blog post regarding the LTS enablement stack and sysadmins. The TLDR as Jorge puts it is, “12.04.2 ISOs are NOT just rolled up updates, they’re 12.04 with newer kernels.” It is good to also note that the 12.04 stack will continue to be maintained for 5 years. Thus, it will get SRUs and the kernel won’t change on you.  I think this is an important thing to note.  However, some folks may want a newer kernel in the LTS life span and for those folks then can evaluate a point release.

Jorge calls out some good recommendations:

  • The 12.04 and 12.04.1 ISO’s are at http://old-releases.ubuntu.com/ - you’ll likely want to keep a set for yourself if you want to roll out with the same exact kernel for your deployments – you’ll probably want to have all three ISO sets on hand depending on your hardware.
  • The original 12.04 stack will continue to be maintained for 5 years, if you don’t need the new kernel, you don’t need to use it.
  • In the past if new hardware rolled out and didn’t work with the LTS you were kind of stuck with either backporting a kernel, or (what I reluctantly did) deploy a non-LTS release until the next LTS came out, at which point you would rebase on the new LTS.)

Be sure to give his blog post and  LTS Enablement Stack Wiki a read. If you have any questions or comments, as always, feel free to give the list (ubuntu-server@lists.ubuntu.com) or a ping in IRC (#ubuntu-server@Freenode).
