Branches / Releases / Build farm

Problems

• One core updates (GCC 5 to GCC 7), broke, then got fixed after the merge
• No Guix release with time-machine

• Installing from the installation image, GCC update, nss-certs embeds characters, locales cause substitutes to fail

  • Install
  • Do a pull
  • Reconfigure fails
• A long time ago, a bug was introduced in to Guix, the guix package was updated, this broke the installation image

• What's the point of having releases?

  • Attracting new users

• Build servers

  • Substitute availability

    • Uncertian how good this is
  • Testing reproducible builds
  • Redundancy
  • All in Europe/Networking
