nixpkgs: Refresh channels and inputs
Rebase the fork branches and refresh nixpkgs, home-manager, and the
approved ancillary inputs. Update kernel and release metadata, adapt
removed package and Home Assistant options, and keep Determinate Nix
on its tested nixpkgs revision to avoid duplicate Boost patches.

Retire Sharry and its public endpoint because copyparty replaces it.
Document the GitHub mirror gate and require real devshell and system
builds in the upgrade validation workflow.

object

Object storage and the Nix binary cache, plus HedgeDoc and wastebin.

Role

Service Port Purpose
MinIO 9000 (S3) / 9001 (console) S3-compatible object storage, s3.nul.ie + *.s3.nul.ie (virtual-host style via MINIO_DOMAIN), console at minio.nul.ie; region eu-central-1; data on the /mnt/minio XFS volume
Harmonia 5000 Nix binary cache at nix-cache.nul.ieharmonia-dev cache serves shill's /nix/store out of a dedicated store view rooted at /var/lib/harmonia (bind-mounted from /mnt/nix-cache), signed with the nix-cache.key secret; a harmonia user with authorized keys exists for cache pushes
HedgeDoc 3000 collaborative markdown notes at md.nul.ie; Postgres on colony-psql; anonymous edits but no anonymous notes, email login, no open email registration
wastebin 8088 pastebin at pb.nul.ie
atticd 8069 currently disabled (services.atticd.enable = false) — an alternative Nix cache that would store locally and sit behind nix-cache.nul.ie; config (including the object/atticd.env secret) is kept around

Everything public is fronted by middleman (see its vhost table). The minio-client is installed and the user's ~/.mc/config.json points at an age-secret config. minio-2025-10-15T17-29-55Z is allowlisted via permittedInsecurePackages (flagged as a TODO).

Network assignments

See the consolidated network assignments table (this box: object).

Backing services

  • colony-psql — HedgeDoc's database (atticd too, when enabled).
  • MinIO buckets back other boxes' services: Gitea LFS/packages (with the middleman MIME hack for Docker manifests), Mastodon's mastodon bucket and the Bluesky PDS pds bucket on toot.
