Remove LTS kernel version

[pierremoreau]

The goal of this image is to easily try the latest version of Nouveau. Having an LTS version of the kernel doesn't bring much wrt that aim (plus it takes almost 100M :-D).

Well, having an LTS version of the kernel is useful to find regressions with the latest kernel. :)

The LTS version is not the latest kernel version. ;-)
I could understand having the latest released kernel version, but I remain in favor of removing the LTS version. :-D

[hakzsam]

I didn't say that LTS is the latest version. :D
I meant, it's better to have different kernel versions to find regressions between them. If having an LTS version only takes 100M, why do you want get rid of it?

[pierremoreau]

Indeed, I read too quickly…

I see mainly two different use-cases to this ISO:

• A user runs a quite old version of the kernel and has some bugs with it/misses some features, so we ask him to test on latest git before going further. Having the latest git will only help if he experiences a regression while trying out the latest git, as it will reduce the number of commits to check for by quite a lot if the regression occurred between the latest kernel and the latest git.
• A user runs an up-to-date (or almost) version of the kernel and wants to run the latest git to try some new features/bug fixes. In that case, I don't see how having the latest kernel will help since he is already running it.

If we want to support regression finding, we should implement #5 and add some scripts to easily bisect the kernel.

I want to get rid of it as I'm trying to reduce the size of the ISO (the latest one weights 974MB and we aren't shipping a full DE on it!!!). The first images were about 500MB, and I'mnot quite sure where the additionnal ~500MB come from. Partly from piglit and some other stuff we added, but still.

Well, go ahead! And if one day we want to re-introduce this LTS version of kernel, it should be easy anyways.

Looks like we are not even including the LTS version on the ISO (see https://github.com/hakzsam/archlive-nouveau/pull/10#issue-166001513)… Need to figure that out.
