This sets the bar very high. I administer berlin.guix.info /
ci.guix.info (same server) and most of the associated build nodes, but I
don’t think people should trust these computers more than their own
computers or those managed by people they personally know.
The build servers do the same work that a user would do who builds
software locally without substitutes; the builders are supposed to
behave just like any other user. (And we can challenge their authority
with “guix challenge”.) I want us to keep in mind that build farms
don’t necessarily deserve any more trust than other computers you don’t
control. Substitute servers are a convenience.
To improve distribution of binaries we are committed to working on
different strategies at the same time:
- improve our processes so that non-critical package changes only hit
the master branch when we have already built the package and made it
available for distribution.
- improve availability of the single server berlin.guix.info by hooking
it up to a CDN via the name ci.guix.info (from which users can easily
opt out by changing their default substitute server to
berlin.guix.info).
- improve redundancy by setting up an off-site fail-over for the head of
the build farm at berlin.guix.info (such as bayfront).
- distribute build artefacts over IPFS without requiring a central
authority
All of these things can be done in parallel by different people. This
increases the project’s resilience and the options that users can choose
from.
