Arch Linux installer ISO — ZFS-on-root or BTRFS, doubles as rescue disk https://git.cjennings.net/archangel/atom?h=v0.8 2026-02-23T17:54:25+00:00 2026-02-23T17:54:25+00:00 Craig Jennings c@cjennings.net 2026-02-23T17:54:25+00:00 urn:sha1:6631521d9f45b73f9b4df76db9148d82af8d57b9 The custom/ directory name was an archiso implementation detail. Renamed to installer/ which clearly communicates that this directory contains the installer scripts and utilities that ship on the ISO. Updated all references in build.sh, Makefile, test-install.sh, and README. 2026-02-23T16:31:01+00:00 Craig Jennings c@cjennings.net 2026-02-23T16:31:01+00:00 urn:sha1:29f464638ab4342d00459d079e93f873962e5409 - Fix cryptkey parameter format: use rootfs: prefix so the encrypt hook finds the keyfile embedded in the initramfs (was treating bare path as a device name) - Switch multi-disk LUKS to sd-encrypt hook which reads crypttab.initramfs to open ALL LUKS containers (the traditional encrypt hook only supports a single cryptdevice) - Create crypttab.initramfs during LUKS initramfs setup - Skip cryptdevice/cryptkey cmdline params for multi-disk LUKS since sd-encrypt reads crypttab instead 2026-01-25T13:36:24+00:00 Craig Jennings c@cjennings.net 2026-01-25T13:36:24+00:00 urn:sha1:06b9cbefbf519da2da13b82e23050d7ada31f3f6 - Add setup_luks_testing_keyfile() for automated LUKS testing - Modify configure_crypttab() and configure_luks_initramfs() for keyfile support - Fix configure_btrfs_initramfs() to preserve encrypt hook when LUKS enabled - Add TESTING=yes to LUKS test configs - Create docs/TESTING-STRATEGY.org documenting testing approach LUKS automated reboot testing remains a work-in-progress due to complexity of sending passphrase to initramfs encrypt hook. Non-LUKS tests all pass: btrfs-single, btrfs-mirror, btrfs-stripe. 2026-01-25T06:10:21+00:00 Craig Jennings c@cjennings.net 2026-01-25T06:10:21+00:00 urn:sha1:dc36ae7bd98ecaadd7b5e9a9d44d4e4e4da532b8 - Store GRUB modules on EFI partition (FAT32) to avoid btrfs subvolume path prefix issues (/@/boot/grub not found) - Create symlink /boot/grub -> /efi/grub for grub-btrfs compatibility - Add sync after grub-mkconfig to ensure FAT32 write completion - Add sync before unmounting to prevent data loss on VM shutdown - Update snapper-firstboot to use /efi/grub/grub.cfg path - Update multi-disk GRUB functions for consistency 2026-01-24T23:29:24+00:00 Craig Jennings c@cjennings.net 2026-01-24T23:29:24+00:00 urn:sha1:9423f1f3253bdf32ae182d1f9d04df55ffb5f9aa - Use -d - flag for cryptsetup stdin key input (matches easy-arch) - Change ((i++)) to ((++i)) to avoid set -e exit on 0 increment - Add btrfs-mirror-luks test config - Update status protocol with sound notifications 2026-01-24T20:28:51+00:00 Craig Jennings c@cjennings.net 2026-01-24T20:28:51+00:00 urn:sha1:613c09c6d4afd4d9c9ea858578ccce29d635941c - RAID1 (mirror) and RAID0 (stripe) for 2+ disks - Multi-disk LUKS with single passphrase prompt - EFI redundancy: GRUB installed on all disks - Pacman hook syncs GRUB updates across EFI partitions - btrfs initramfs hook for multi-device assembly at boot 2026-01-24T18:23:45+00:00 Craig Jennings c@cjennings.net 2026-01-24T18:23:45+00:00 urn:sha1:3fc34866ab9092445039f1da3c9f71c60f30f2ee - Fix GRUB cryptodisk: configure_grub() heredoc was overwriting LUKS settings added by configure_luks_grub(). Moved LUKS GRUB config (GRUB_ENABLE_CRYPTODISK=y, cryptdevice cmdline) into configure_grub() after the heredoc writes the base config. - Fix ISO bloat: archsetup copy was including vm-images (17GB). Changed from cp -r to rsync with exclusions for vm-images, test-results, .qcow2, and .iso files. ISO now 2.0GB. - btrfs-luks VM test now passes. 2026-01-24T11:33:13+00:00 Craig Jennings c@cjennings.net 2026-01-24T11:33:13+00:00 urn:sha1:94af83c1c8446ef1a564cff8aec5487afa47693e - Add LUKS functions to btrfs.sh (create/open/close container) - Add crypttab configuration for boot - Add encrypt hook to mkinitcpio HOOKS - Add cryptdevice parameter to GRUB cmdline - Add get_btrfs_encryption_choice and get_luks_passphrase prompts - Add LUKS_PASSPHRASE to config variables - Update show_summary and print_btrfs_summary for encryption status - Add btrfs-luks.conf test config VM test pending. 2026-01-24T11:23:49+00:00 Craig Jennings c@cjennings.net 2026-01-24T11:23:49+00:00 urn:sha1:f96453e556c48eced30b16214575d48dd9a61fee - Add GRUB serial console configuration for headless/VM testing - Add GRUB_BTRFS_OVERRIDE_BOOT_PARTITION_DETECTION for btrfs - Fix snapper-firstboot script (use echo instead of HEREDOC) - Add dbus.service dependency to firstboot service - Remove duplicate rootflags from GRUB_CMDLINE_LINUX VM test verified: GRUB boots, all subvolumes mount, snapper works. 2026-01-24T05:58:07+00:00 Craig Jennings c@cjennings.net 2026-01-24T05:58:07+00:00 urn:sha1:bf62150d61d3e52b07095be21aff9ac5abe9d03f - Fix GRUB config path (remove GRUB_BTRFS_GRUB_DIRNAME, use default) - Create snapper config manually (D-Bus not available in chroot) - Create genesis snapshot with btrfs command (not snapper) - Add btrfs-single.conf test config - Update test-install.sh to copy lib/ directory - Update test-install.sh to handle btrfs verification VM test now passes for btrfs single-disk installation.
