A long-overdue announcement... Some months ago, Nikita and I asked the FSF sysadmins for a (virtual) machine to host a Hydra instance. They offered us a 4-core VM (I think?), known as hydra.gnu.org. Nikita installed Nix and Hydra, and I finished the setup of Hydra. There were various issues needing to be addressed in Hydra=E2=80=99s support for Guix[*]. Anyway, if you go to , you=E2=80=99= ll see the packages for =E2=80=98master=E2=80=99, and at you=E2=80=99ll see the packa= ges for =E2=80=98core-updates=E2=80=99. There are still glitches here and there on the web UI and setup. You=E2=80= =99re welcome to report them and help fix them. Ludo=E2=80=99. [*] My initial plan was to use it both for continuous integration (CI) of Guix itself (that is, running autoreconf && make dist && ./configure && make check && make install of Guix), and CI of the distro. In that plan, CI of Guix itself would be done with Nix (via the release.nix file that we have), whereas CI of the distro would be done with Guix (the hydra.scm file). But Guix=E2=80=99s distro doesn= =E2=80=99t need /bin/sh in its chroot, whereas Nixpkgs does, and a single daemon cannot handle both setups. So we=E2=80=99d have had to either run our builds in a chroot that includes /bin and more, at the risk of introducing impurities and not catching other errors, or we=E2=80=99d h= ave been unable to build Guix itself. The solution I ended up with was to rely on a pre-installed version of Guix for bootstrapping: https://github.com/NixOS/hydra/commit/f3aa48978e1f0922094f159c762bf8664= ae40ed2 (Anyone willing to rewrite Hydra in Guile? :-))
