Arch Linux installer ISO — ZFS-on-root or BTRFS, doubles as rescue disk https://git.cjennings.net/archangel/atom?h=main 2026-04-13T04:16:04+00:00 2026-04-13T04:16:04+00:00 Craig Jennings c@cjennings.net 2026-04-13T04:16:04+00:00 urn:sha1:a15a92cf36d2460784587b3fa6f586e94e9ff6ab Pull the single-vs-multi-disk and LUKS-vs-no-encryption branching out of install_btrfs() into five helpers in lib/btrfs.sh: - btrfs_open_encryption — LUKS open + fill devices array - btrfs_make_filesystem — create_btrfs_volume dispatch - btrfs_configure_luks_target — in-chroot LUKS config - btrfs_install_grub — GRUB primary + multi-disk mirror - btrfs_close_encryption — LUKS close (cleanup) Helpers use namerefs (local -n) to take the caller's arrays as locals instead of promoting them to globals. install_btrfs() drops from ~99 lines of nested if-then-else to a ~45-line flat sequence of named stages — matching the style of install_zfs(). Behavior preserved — this is pure code movement, no new disk/LUKS operations. No unit tests added for the new helpers: they all wrap real LUKS/mkfs.btrfs calls that need block devices and root; VM integration tests in scripts/test-install.sh remain the source of truth. .shellcheckrc: disable SC2178 (nameref array heuristic) and SC2153 (globals from sourced files) — both recurring false positives. make test: 65/65. shellcheck clean. 2026-04-13T04:10:17+00:00 Craig Jennings c@cjennings.net 2026-04-13T04:10:17+00:00 urn:sha1:bc613e72238f864a597777826d1f9cc533c4cffa Extract the pacstrap package list into pacstrap_packages(filesystem) in lib/common.sh (common + filesystem-specific). install_base() now dispatches on FILESYSTEM for both the archzfs-repo-append and the package list. install_base_btrfs() deleted; install_btrfs() call site updated to invoke install_base. Old: 49 + 38 lines of ~95% copy-paste. New: 32 lines + a 20-line pure helper. 7 bats tests cover: zfs has zfs-dkms/zfs-utils, btrfs has btrfs-progs + grub + grub-btrfs + snapper + snap-pac, each flavor excludes the other's specifics, common packages are in both, unknown filesystem returns status 1, output is one-per-line. make test: 65/65. 2026-04-13T04:07:46+00:00 Craig Jennings c@cjennings.net 2026-04-13T04:07:46+00:00 urn:sha1:9f6c75916cee8cb65b21b71c69f62d080818ad63 Extract the prompt/confirm/min-length loop into prompt_password() in lib/common.sh using a nameref for the output variable, so UI output stays on the terminal (no command-substitution capture) and the three callers collapse from ~30 lines each to a single helper call. - get_luks_passphrase() — min 8 chars - get_zfs_passphrase() — min 8 chars - get_root_password() — no min (was unchecked before; preserved) 5 bats tests added: match+min-ok path, length-retry loop, mismatch-retry loop, min_len=0 disables check, empty passphrase when min_len=0. make test: 58/58. 2026-04-13T04:05:09+00:00 Craig Jennings c@cjennings.net 2026-04-13T04:05:09+00:00 urn:sha1:88d2fafe410a82dfa3534d7c0466689997407a0c lib/disk.sh:mount_efi() was shadowed by installer/archangel:mount_efi() (different signature, no-arg ZFS-specific) and had zero callers. lib/disk.sh:select_raid_level() was superseded by get_raid_level() in archangel and also had zero callers. Both removed. 2026-04-13T03:58:01+00:00 Craig Jennings c@cjennings.net 2026-04-13T03:58:01+00:00 urn:sha1:19f4624749228fcbe385d1edf1d2542c036440ff Peel the testable pieces of get_raid_level() out of the 1600-line installer monolith into installer/lib/raid.sh: - raid_valid_levels_for_count(count) — replaces the inline option-list builder in get_raid_level() - raid_is_valid(level, count) — useful for unattended-config validation - raid_usable_bytes(level, count, smallest, total) — usable-space math - raid_fault_tolerance(level, count) — max tolerable disk failures archangel now sources lib/raid.sh and uses raid_valid_levels_for_count for the fzf option list. Fzf preview subshell still inlines its own usable-bytes arithmetic (calling exported lib functions across preview subshells is fragile; left for a later pass). 30 bats tests in tests/unit/test_raid.bats cover the full enumeration table, every valid/invalid level-vs-count combo from 2 to 5 disks, mixed-size mirror, and unknown-level error paths. make test: 53/53. 2026-04-13T03:20:48+00:00 Craig Jennings c@cjennings.net 2026-04-13T03:20:48+00:00 urn:sha1:33ff55507895af2c29a20ec7e7e707d317cb8ef1 velox-{zfs,btrfs}.conf contain LUKS/ZFS passphrases and root passwords.

Inlined zfs_preflight into archangel and dropped the source line. Removes a trap where fixes appear to be "mirrored" but only one copy actually runs. 2026-04-13T02:55:02+00:00 Craig Jennings c@cjennings.net 2026-04-13T02:55:02+00:00 urn:sha1:64260df38906e68b3d75169b8cae3b69715f5bc6 - /tmp on ZFS breaks systemd-tmpfiles-clean (statx ENOLINK on PrivateTmp paths). Use tmpfs via fstab instead; keep zroot/var/tmp. - zfs-pre-snapshot gains a 60s lockfile in /run so burst transactions (archsetup produced 357 snapshots in one run) collapse to one. Both fixes mirrored in installer/archangel and installer/lib/zfs.sh. Already applied and verified on velox. 2026-04-10T16:26:56+00:00 Craig Jennings c@cjennings.net 2026-04-10T16:26:56+00:00 urn:sha1:77b9caac5a6bb5c338f691fdadd2f781557a9d7b ZFS and Btrfs tested on bare metal.
