Thanks for letting me know. I didn't know this was happening. The immediate solution is for me to make sure the tarballs have built before committing the updates. I already do this for x86_64 and I can start doing it for aarch64 too. > * Using linux-libre's git repository. We could do this. The decision is up to the maintainers, ultimately. I'd rather we did not because linux-libre is not the "upstream" of the kernel in a meaningful way (they do not develop or fix bugs), and it's not "source code" in the GNU sense, which is the "preferred form of the work for making changes in it": http://www.gnu.org/licenses/gpl-faq.en.html#GPLOtherThanSoftware Not to mention that cloning a 1 GB Git repo is rather expensive compared to downloading a tarball, and thus also suboptimal for the ARM boards that can't easily deblob. Although if people are building the linux-libre tarballs, they are also compiling, which is of course way more expensive. > * Using the linux-libre tarballs.

As you say, these tarballs are not available for very long. I think this option is not practical for that reason. > * Bump the timeouts on ci.guix.gnu.org for linux-libre so that the > deblob scripts actually get a chance to finish.
