From d2aeb0021df6d097cfa6267d31cd37af0d2469c0 Mon Sep 17 00:00:00 2001 From: Tomas Srnka Date: Fri, 24 Jul 2026 11:35:21 +0200 Subject: [PATCH 01/19] feat(orch): distro-aware template provisioning (systemd family: Fedora/RHEL/Arch) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Template builds are Debian/Ubuntu-only today: provision.sh hardcodes apt/dpkg, Debian package names, the /lib/systemd/systemd init path and the chrony unit, so a Fedora/RHEL/Arch base image fails opaquely during provisioning. This makes provisioning distro-aware by keying on the base image's DECLARED /etc/os-release ID (ADR-010) — not by probing which package manager exists (the axis rejected in #2941). Each supported family is a declared Profile in a new `phases/base/distro` package; provision.sh selects the profile in-guest by $ID via a selector generated from that registry, and uses its package set, package-manager functions, init path, chrony unit, admin group and CA handling. An unsupported distro exits fast with a clear, customer-visible error. - new `phases/base/distro`: Profile registry (debian/ubuntu, RHEL family incl. rocky/alma/centos/rhel/ol/amzn, arch) + generated shell selector + unit tests. - provision.sh: os-release detect + selector; profile-driven package check/ install, init-link, chrony enable, CA-bundle ensure. Debian package set/query/ init path preserved (AC2). - rootfs.go: drop the static Debian chrony.service symlink; provision.sh now enables the distro-correct unit (chrony vs chronyd). - configure.sh: adduser -> useradd (portable); admin group sudo||wheel. Scope: systemd family only (v1). Alpine (OpenRC/musl) is explicitly rejected and tracked separately. Egress-proxy CA trust on RHEL (envd /etc/pki path) is a follow-up. Refs FEAT-145 / IMPL-145.

Ship /etc/systemd/system-preset/00-e2b.preset ('enable envd.service') so every preset-all — RPM scriptlet or first boot — enables envd instead. 2. The DEFAULT USER build step used Debian's 'adduser --disabled-password --gecos' (exit 2 on Fedora, where adduser is useradd) and 'usermod -aG sudo' (no sudo group there). Ported to useradd + a sudo-then-wheel fallback, mirroring configure.sh (W1 T4). With these plus the CA-bundle fix, the Fedora 40 template build completes on real x86 KVM.

Alpine profile (apk, busybox init -> OpenRC runlevels): the OpenRC setup replaces the one-shot provisioning inittab with the real boot sequence, wires the sysinit/boot runlevels a container image ships without, and enables envd via the baked /etc/init.d/envd (supervise-daemon, mirrors envd.service incl. the CA-store seeding; inert on systemd images).

The provisioning scripts used during template build call `apt` and expect Debian-specific package names and file locations. \ No newline at end of file +- Custom template builds support base images from the declared distro families (FEAT-145): **Debian/Ubuntu** (apt), the **RHEL family** — Fedora, RHEL, CentOS Stream, Rocky, Alma, Oracle Linux, Amazon Linux — (dnf/microdnf), **Arch** (pacman), and **Alpine** (apk, OpenRC). The distro is resolved from the image's `/etc/os-release` `ID` — never by probing for package managers (ADR-010). Images without an os-release identity (pure-Nix, distroless, scratch) or from an undeclared family are rejected fast, with a build-log error naming the reason and the supported families (see `pkg/template/build/phases/base/distro`). Minimal/restricted-repo images (e.g. RHEL UBI) may fail provisioning if their repos don't carry the required packages; the failure is surfaced in the build log. \ No newline at end of file From 459b5880bb0f42d30626a57409427adaa8acb062 Mon Sep 17 00:00:00 2001 From: Claude Fable 5 Date: Sat, 25 Jul 2026 09:26:04 +0000 Subject: [PATCH 14/19] feat(orch): premade-NixOS profile + bare-image-proof provisioning boot; explicit failure paths everywhere MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit NixOS tier (qa.md QA13 proposal, operator-approved): a 'nixos' profile for PREMADE images built from the E2B NixOS configuration — no package manager to drive (everything is declared in the image), stage-2 init at the profile symlink, and a Bootstrap hook that puts the baked busybox's applets on PATH (no FHS userland exists before the first activation). The provisioning boot itself is now self-contained on the baked busybox: - rcS drives mkdir/mount through it (bare images have neither on PATH) - busybox init hands any inittab line with shell metacharacters to /bin/sh, which bare images don't have — the pipeline moved into a baked runner script and every inittab entry is a plain exec; fsfreeze falls back to sync-only with a message where util-linux is absent Failure-path policy (operator directive): no '|| true' silencing — explicit checks with stated code paths. CA refresh failures now fail provisioning loudly; missing OpenRC scripts / skel / passwd are checked and logged as deliberate skips; user creation and admin-group failures are hard errors; cert seeding is one shared warn-and-continue script (e2b-seed-certs) used by both envd services instead of two silent fallback chains.
