Sizes come from CI run 48 (4ca2f45): ISO, rootfs, installed size and the largest packages of both editions. The bloat table lists what each item costs, why it is bloat and what is done about it; product decisions are listed separately and not acted on.

…image From the 19 October build report (installed size): linux-zen-headers 325 MiB, opencv 113 MiB (only spectacle needs it), plus the legacy xorg-server and xf86 driver stack and a third system-information tool. - Setup downloads the running kernel's headers with the NVIDIA DKMS driver, the only thing that builds modules. The kernel package comes from the pkgbase file of the running kernel. - The artools library patch that reads the kernel version from /usr/lib/modules now applies to every kernel: the stock one no longer has headers to read it from. - The desktop has its own screenshots, so spectacle goes; both sessions are Wayland, so the X stack becomes xorg-xwayland, as in Lite. - Five packages listed twice are listed once. - cupsd is no longer enabled by default (live session and Setup); the packages stay.

A workspace of its own (release profile: opt-level z, LTO, panic=abort, stripped; about 550 KiB) with the crate segctl and the binary seg. One dependency, lexopt. - seg info: distro, kernel, init, uptime, RAM, packages, disk. - seg svc list|enable|disable|start|stop: OpenRC, runit, dinit and s6, detected from PID 1, /run, then the installed files. - seg clean: orphans, pacman cache beyond the newest 2 versions (a port of libalpm's vercmp), rotated logs, ~/.cache size. Dry run by default. - seg tune light|balanced|performance: vm sysctls, CPU governor, I/O scheduler per disk type; saved to /etc/sysctl.d/99-seg.conf. - seg zram on|off|status: zstd swap in memory, half the RAM. - seg doctor: failed services, missing firmware, low disk space, a stale db.lck, a broken keyring, each with its fix. Root is checked up front, unwrap/expect/panic/indexing are compile errors outside tests, output ends quietly on a closed pipe. 77 unit tests cover every parser and the file-writing parts against a fake /sys, /proc, /etc. Also run in an Artix container: info, doctor, clean, tune, zram status, svc against the real dinit layout.

- pkg/segctl: PKGBUILD, install script (enables seg-zram and seg-tune, choosing the init by what is installed, so it works in the build's chroot), Makefile. Ships seg, the services for OpenRC, runit and dinit, the balanced profile and the weekly fstrim job. - build-in-container.sh builds it from tools/seg into the same local [seglinux] repository; both profiles list segctl; check-packages.sh and online-packages.sh know it is built locally. - Setup enables seg-zram and seg-tune on every installation, and no longer cupsd (installed, not started). - zram-setup (run by udev at module load) hands over to seg zram on when seg is installed, so systems updated before segctl keep their zram. - Fixes a stale path in a comment of the fstab code, and the swap partition test now looks for the fstab line instead of the word zram.

…itions - /etc/makepkg.conf.d/10-seglinux.conf sets MAKEFLAGS="-j$(nproc)" (the generic x86-64 code generation stays, no -march=native). - udev-ioschedulers.rules: the KERNEL globs (sd[a-z]*, nvme[0-9]*n[0-9]*) also matched partitions, which have no queue/scheduler to write, so udev logged an error for every partition. Only whole disks are matched now, and virtual disks (vd*, xvd*) get none like seg tune sets, since their host does the scheduling. Checked with udevadm verify. pacman.conf already has Color and ParallelDownloads = 5.

Rust command-line tools from the Artix repositories (no AUR), chosen because each is small and replaces a daily habit: - ripgrep (rg) searches folders far faster than grep -r and skips what .gitignore skips; fd finds files by name without find's syntax. - eza is ls with colors and git status (aliased as ll and la only); zoxide gives z, which jumps to the folder you use most. They add a few MiB (the next build report gives the exact figure) against the 438 MiB the earlier commits take off (linux-zen-headers 325.1 MiB and opencv 112.8 MiB, from the 19 October build report, plus the X server). Not added, with reasons in docs/lean-audit.md: bat, dust, bottom, procs and sd (they replace nothing that is installed), helix (a runtime of grammars next to nano), alacritty (the terminal is the maintainers' call), zellij, sudo-rs.

- A seg job: cargo fmt --check, clippy with -D warnings (with and without the test cfg, so the unwrap/expect ban is enforced), tests, and the release binary's size in the job summary. It fails if seg gains a dependency besides lexopt. - udevadm verify on data/system/*.rules. - A package may be listed only once per profile and init; the five repeats this found in the full profile are gone. - shellcheck also covers zram-setup (it was missing), the seg services, the weekly fstrim script, segctl.install and rust-tools.bashrc.

Builds both editions on seg/rust-lean-overhaul without publishing anything (the ISO workflow cannot be started from here), lists what the system image contains and does not contain, and boots Lite in QEMU, logs in on a text console and runs seg. Removed again once the branch has been checked. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0119819Vrp5vJojQCT1CjWog
