+--------------------------------------------+ | Glacier roadmap | +--------------------------------------------+ What's left to build, in priority order. Status as of 2026-10-07. Design detail lives in the companion docs; this file says WHAT and in what order, and links to WHERE: SECURITY_DESIGN.txt integrity, scope separation, refusal matrix PACKAGE_SCOPES.txt layout, link routing, /etc config handling IMAGE_DESIGN.txt system images as bootstrap output, sysroot REPO_DESIGN.txt remote repositories, signing, keyring GLACIER_BOOTSTRAP.txt glacier-bootstrap plan, prerequisites, decisions Mark an item [DONE yyyy-mm-dd] rather than deleting it, so the history stays readable. CLAUDE.md "Known open items" tracks small bugs; this file tracks work. +--------------------------------------------+ | 1. Install Everest with glacier alone | +--------------------------------------------+ The critical path: from "QEMU boots an initramfs assembled by a script" (~/Projects/everest) to "glacier installs a system". 1.1 [DONE 2026-10-05: see CLAUDE.md "Install root / sysroot" and tests/sysroot_alpine.sh.] sysroot in the library (IMAGE_DESIGN section 3). Every path is hardcoded to /glacier and /usr. Needs separate install-root (where bytes are written) and runtime-root (what symlink targets say). The trap: prune_stale_links follows absolute links, so a naive prefix would judge the image's links against the HOST's filesystem. Required test: an image build leaves the host's /usr and /glacier byte-identical. 1.2 [DONE 2026-10-05: -R/--root, strict by default under -R, --strict.] syspkg --root DIR (refuses unless DIR and its ancestors are root-owned and not group/world-writable) and --strict (any link refusal fails the transaction; an image's /usr starts empty). gl_create_fs_tree already takes a root prefix. 1.3 [DONE 2026-10-06: glacier-ng/glacier-bootstrap, GLACIER_BOOTSTRAP section 10; Everest's initramfs is built with it and boots.] glacier-bootstrap, local mode (GLACIER_BOOTSTRAP.txt sections 1-6). Template index -> resolve -> verify -> syspkg --root, one transaction. Never writes into TARGET itself. [DONE 2026-10-07: repositories. TARGET's repos.conf + keys come from a package (Everest: everest-repos); bootstrap then runs syspkg -R TARGET -y, which reads TARGET's own keyring; exit 7 on a failed fetch. GLACIER_BOOTSTRAP section 10. Later, maybe: an opt-in copy of the host's repos.conf (pacstrap's mirrorlist).] 1.4 [DONE 2026-10-06: built by ~/Projects/everest/scripts/container.sh, in templates/minimal.template, boot-verified in QEMU; full regression passes.] Packages for glacier itself, so an installed system can manage itself: luajit, libarchive (+ zlib), libconfig, libglacier-ng, glacier-ng (syspkg, gpkg, gstore), doas. Decided 2026-10-06: - base: luajit, zlib, libarchive, libconfig, libglacier-ng, glacier-ng. extra: doas (replaceable, e.g. by sudo). - glacier-ng ships syspkg, gpkg and gstore only. glacier-bootstrap, gbuild, gworld and gsha256sum become a later "glacier-tools" package in extra (after the release, which brings a real install Makefile). - everest-bootscripts ships /etc/doas.conf: `permit :wheel`, plus `permit nopass :wheel as root cmd /usr/bin/gstore args -n`. - Layout: scripts + lib/ in usr/lib/glacier-ng/, usr/bin/{syspkg, gpkg,gstore} symlink into it (realpath lands in the store, lib/ beside it); gpkg moves to the same real-path loading. As built: zlib 1.3.2, libarchive 3.8.9 (gzip + tar only; every other codec, crypto library and front-end disabled), libconfig 1.8.2 (no C++), luajit 2.1.1788856981 (commit c6ffc141), libglacier-ng 4.0.0, glacier-ng 4.0.0, doas 6.8.2 (OpenDoas, no PAM, no timestamp). The doas.conf rule is given for both `cmd gstore` and `cmd /usr/bin/gstore`: OpenDoas matches what was typed. luajit is linked -static-libgcc, since Everest ships no libgcc_s (see section 6). 1.5 [DEFERRED 2026-10-06 by the user: manual installation is one of Everest's main features, so the installer comes later. 3.1 is next.] [2026-10-07, the user: a manual install works from a live Everest system or any Linux host; the live system is the preferred, officially supported way. The user is trying the first disk install (QEMU) themselves.] The installer. Undesigned; needs its own design session (SECURITY_DESIGN section 10). Partitioning, a bootloader or an EFI-stub kernel on the ESP, copying the kernel there (a symlink won't do on FAT), a disk image. Already done on this path: hash verification, package symlinks, the merged-/usr tree on syspkg -n, /etc config handling, a QEMU-bootable musl + busybox + linux + everest-bootscripts set. +--------------------------------------------+ | 2. Package-manager features | +--------------------------------------------+ 2.1 UPGRADES. Spec (2026-10-04): - Replacing an installed version is `-lO` (local file) — plain -l refuses ("extra::foo 1.0.0 is already installed.", nothing more). [DONE 2026-10-04] - The replaced version is BACKED UP: its files compressed into /backup///-.gpkg + .sha256, a complete installable package (saved manifest included). KEEP_OLD in glacier.conf = how many backups to keep per package (0 = none). No default: glacier.conf ships with KEEP_OLD = 1, and an operation that would replace a version refuses if it's missing or invalid. [DONE 2026-10-04] - A restore interface for backups: later. (A backup can already be reinstalled with -lO.) - `gpkg -u` / `syspkg -u` = upgrade from a REMOTE repository; waits for 3.1, like -f. [DONE 2026-10-07: REPO_DESIGN section 6, "As implemented".] - /etc follows the existing config rules regardless. 2.2 [DONE 2026-10-07: REPO_DESIGN section 6, "As implemented".] gpkg -f / syspkg -f: MERGE. Spec (2026-10-04): exactly like -l, except the package comes from a remote repository by name instead of from a local file. Same summary, verification, scope rules and transaction. Depends on 3.1 (remote repositories + signing): until then there is nothing safe to fetch from. 2.3 Dependencies. [DONE 2026-10-05; automatic closure DONE 2026-10-07 with -f/-u (REPO_DESIGN section 6).] Spec (2026-10-05), all three checks in one pass, no override flag, every problem reported (one line each) before failing: - A dependency's PKG_VER is a MINIMUM (installed >= PKG_VER). Matched by name, any repo. - A user package's dependency may be met by system scope or the user's own scope. syspkg -x checks system-scope dependents only. - Conflicts: both directions (new lists installed, or installed lists new), by name; PKG_VER is ignored. - Missing dependencies REFUSE until 3.1; then automatic closure (GLACIER_BOOTSTRAP 9e). - Index records auto vs explicit now: /.glacier-auto in the store, index line repo::name::version::auto|explicit. - Messages: extra::foo requires bar >= 1.2.0, which is not installed. Removing base::musl breaks extra::foo. extra::foo conflicts with extra::bar. - install: refuse if a dependency isn't installed (or in the same transaction); - REMOVE: refuse to remove a package others depend on. Today nothing stops `syspkg -x musl` from breaking every binary on the system. Highest-value item in this section; - conflicts: refuse to install a package that conflicts with an installed one. 9e DECIDED 2026-10-05: automatic closure, after 3.1 (see above). 2.4 Queries: list installed packages, show a package's details, find which package owns a file. The index has the data; no CLI shows it. 2.5 Rollback. Every commit moves the previous state to old/ and then deletes it. Keep it (or the last N), plus a command to return to it. Interacts with 2.1's KEEP_OLD. 2.6 [DONE 2026-10-05: refused in every scope, before the prompt and at commit (deps.c check_collisions).] File conflicts between packages: two packages shipping the same path — whichever links last silently wins. Detect and refuse. 2.7 glacier.conf parsing. [DONE 2026-10-04 for integers: gl_conf_get_int, no defaults, missing/unreadable/wrong-type are distinct errors.] Still open: rejecting UNKNOWN keys (CLAUDE.md bug 10's lesson — a misspelled KEEP_OLD currently reads as "not set", which at least fails loudly). 2.8 gstore: -s (sync) is a stub; there's no restore command although gstore -b's output tells you to run -r (gl_restore_istore exists). 2.9 User-scope config files: user packages still link etc/ into a links tree that's rebuilt on every commit. 2.10 Hardlink entries in package archives are skipped at extraction. +--------------------------------------------+ | 3. Security | +--------------------------------------------+ 3.1 Remote repositories + signing (authenticity, keyring). The agreed next major item. Design: REPO_DESIGN.txt (2026-10-06; decisions in sections 1 and 10, order of work section 9). [IN PROGRESS 2026-10-06: steps 1 and 2 DONE (gsign; the local base rule, repos.conf + keyring, gbuild -k, bootstrap carries .sig, Everest signs with everest-2026) and 3 (grepo; the signed index; syspkg/gpkg -y refresh with rollback state) DONE; step 4 (-f with closure, -u, the cache) DONE 2026-10-07; step 5 (glacier- bootstrap -r) next, then 6 (user repos).] Unblocks remote glacier-bootstrap. Until then, GLACIER_BOOTSTRAP's pinned templates are the safe bridge for remote fetches. 3.2 Hash verification lives in the CLIs' shared module. A third-party tool calling gl_install_pkg directly isn't verified. Consider moving it into the library, like the base-in-user-scope refusal. 3.3 Manifests don't record the SYS_PROFILE they were built under, so a package built for the wrong target can't be detected. 3.4 gstore -n accepts UIDs with no passwd entry (pre-provisions a directory nobody owns yet; a typo creates a stray one). +--------------------------------------------+ | 4. Build tooling | +--------------------------------------------+ 4.1 gbuild system profiles (-P ARCH-LIBC[-FEATURE...]) and gworld's SYS_PROFILE recipe field. CLAUDE.md described both as done; neither exists in the tree (only one gbuild, in glacier-ng). Today the target libc is decided by where gbuild runs (~/Projects/everest builds in Alpine for musl). [2026-10-07, the user: Everest will run under glibc as well as musl, so profiles are a real requirement, not a nicety. The libc is picked at install time (Gentoo/Void style), one per system. Open: how packages are kept apart (section 6).] 4.2 Move ~/Projects/everest's per-package gbuild commands into gworld recipes once 4.1 lands. +--------------------------------------------+ | 5. Performance (not urgent) | +--------------------------------------------+ 5.1 gl_relink_store / gl_rebuild_index rescan the whole store on every commit. Fine at current scale; a dirty set is the fix. +--------------------------------------------+ | 6. Decisions waiting | +--------------------------------------------+ - Images are only ever bootstrap OUTPUT (IMAGE_DESIGN 9a / GLACIER_BOOTSTRAP 9a). - Where the pinning helper lives (GLACIER_BOOTSTRAP 9f). - 2.1's open questions a-d (upgrade backups). - extra vs community: should they ever behave differently? - The installer (1.5), deferred. - libgcc (1.4): luajit is built with -static-libgcc because Everest has no libgcc_s. Claude's call, not yet reviewed; the alternative is a GCC runtime package in base, which later C++/unwinding packages would need anyway. - glibc and musl (4.1): DECIDED 2026-10-07 that the user picks the libc at install time, like Gentoo's profiles / Void's glibc and musl ISOs; one libc per system. Still open: how packages are kept apart (Claude recommends both per-libc repos, as Void, AND a libc field in manifest + index that the library refuses on a mismatch with the system's recorded libc). +--------------------------------------------+ | 7. Done | +--------------------------------------------+ [DONE 2026-10-07] -f and -u from repositories (3.1 step 4; 2.1's -u, 2.2, 2.3's closure): first repo serving a name wins; missing deps added auto, too-old ones upgraded; downloads in /cache/REPO, hashed against the signed index, manifest must match the entry, deleted after commit. tests/fetch_alpine.sh (84 checks, 17 mutants). [DONE 2026-10-06] Packages for glacier itself (1.4): zlib, libarchive, libconfig, luajit, libglacier-ng, glacier-ng in base, doas in extra; everest-bootscripts 1.1.0 ships /etc/doas.conf. Everest's initramfs installs all 11 packages; in QEMU, syspkg/gpkg run from the store, syspkg -x musl is refused (dependents), a wheel user runs doas gstore -n without a password, then gpkg -l. gpkg loads lib/ from its realpath. tests/installed_alpine.sh (30 checks) installs glacier in that layout and runs it from the store. Found on the way: gbuild's clone warning broke builds from a commit hash (CLAUDE.md bug 28); syspkg/gstore never checked the ancestors of libglacier-ng's store dir, which the installed .so's live in (bug 29; both mutations caught). [DONE 2026-10-07] glacier-bootstrap configures repositories (1.3): syspkg -R's -y/-f/-u use TARGET's own repos.conf and keys (each file's real path must stay inside TARGET); bootstrap runs syspkg -R T -y when T's repos.conf gives a url (exit 7 on failure, a warning when none does). Everest: new base package everest-repos 1.0.0 (/etc/glacier/repos.conf + everest-2026.pub), moved out of everest-bootscripts (now 1.3.0). bootstrap_alpine.sh 100 checks (6 mutants, all caught); repo/fetch suites updated; full regression green; Everest rebuilt and booted. [DONE 2026-10-06] glacier-bootstrap, local mode (1.3): template (NAME=, PKG=name ver [sha256:pin]; strict), verified private copies handed to syspkg -R in one transaction, template-level dependency / conflict / name checks, -n, -t. tests/bootstrap_alpine.sh (77 checks, 11 mutations caught). ~/Projects/everest's initramfs is now a glacier-installed system (templates/minimal.template), booted in QEMU: /glacier/sys, merged-/usr links into the store, /etc copied, a non-root user runs busybox. [DONE 2026-10-05] syspkg -R/--root DIR + --strict (1.2) and file collisions (2.6): gl_check_sysroot (root-owned, non-symlink, not group/world-writable, every ancestor), ctx->strict (a would-be link refusal fails the transaction before the prompt and at commit; -O still displaces), two packages shipping one path refused in every scope. tests/root_alpine.sh (50 checks, 7 mutations caught). gpkg silently ignored unknown flags (CLAUDE.md bug 27). [DONE 2026-10-05] sysroot in the library (1.1): *_at contexts and gl_init_sys_at, install paths in the context with runtime translation at link/prune/displace, /usr and /etc under the sysroot, user scope refuses one. tests/sysroot_alpine.sh (33 checks, 8 mutations caught). Found on the way: live-context removal deleted foreign files (CLAUDE.md bug 26). [DONE 2026-10-05] Dependencies and conflicts (2.3): src/deps.c (gl_check_plan before the prompt; gl_check_txn enforced by gl_commit_transaction; live-context installs/removals checked inside gl_install_pkg/gl_remove_pkg), index field 4 auto|explicit + .glacier-auto + gl_set_pkg_auto, gl_read_pkg_manifest split out of gl_install_pkg. tests/deps_alpine.sh (41 checks, 8 mutations caught). Found on the way: the live index was rewritten through a seeded hardlink (CLAUDE.md bug 25), tests/test_index_abort.lua. [DONE 2026-10-05] System scope world-readable (found while specifying 2.3): /glacier/sys was root 0700 throughout, so non-root users could run nothing syspkg installed. Dirs 0755 / index 0644, and created modes no longer depend on the umask. tests/sys_perms_alpine.sh. [DONE 2026-10-04] Version replacement + backups (2.1): -lO replaces, KEEP_OLD backups, gl_backup_pkg / gl_prune_backups / gl_conf_get_int, the manifest saved in the store (.glacier-manifest), add_to_archive learns symlinks (gstore -b silently dropped them too), gpkg modifier flags (-O -S -V) order-independent so `gpkg -lO` works. tests/upgrade_alpine.sh (29 checks). [DONE 2026-10-04] Correctness batch: - gbuild: autotools detected before a bare Makefile (bug 8 had regressed); --cross-prefix fixed (its option-table key was misspelled); -v/--version print the version as documented, with --verbose for verbose output. - gpkg -x: summary resolved from the index (was "unknown::pkg 0.0.0"); a package that isn't installed fails before the prompt. - gpkg: precise refusal for a missing / squatted / loosened user directory (was "No index found"), via gl_usr_base_status. - gpkg -h lists -l and -S; -f/-u described by the 2.1/2.2 specs. - Up-to-date reinstall logs once. - Link conflicts reported once, by the package that has them, not again on every later system commit (.glacier-fresh marker). - A failed extraction no longer leaves a half-extracted version dir (in a live context, every retry then said "already installed"). - Dead old-layout code removed from pkg.c (gl_prepare_pkgdir and the gl_usr_* / gl_sys_* dir_t constants). - tests/glacier_ffi.lua is a wrapper over lib/glacier_cdef.lua; its own copy had already drifted (missing GL_INSTALL_ERR_SCOPE). - Dockerfile.arch / .debian moved to the per-uid layout (root-owned /app, libglacier-ng built from source, the gstore -n doas rule). [DONE 2026-10-04] Hash verification; package symlinks; per-uid user layout + doas gstore -n; syspkg -n top-level tree; /etc config handling (copy + .new); -O/--overwrite; everest-bootscripts.
