Nix
and NixOS
releases are now built in Hydra, the new Nix-based
continuous build system. Hydra replaces our old Nix-based
build farm, which will be phased out soon. There are
several advantages over the old build farm: the build tasks for
a project are scheduled and published separately, so that for
instance a (fast) tarball build doesn’t have to wait for a
(slow) Cygwin build; build results are stored in a database,
which will enable all sorts of interesting queries; better error
reporting; a better web interface; and much more. We have
written a draft
paper about Hydra. There are some instructions
available about how to set up your own Hydra server.
