Arch Linux installer ISO — ZFS-on-root or BTRFS, doubles as rescue disk https://git.cjennings.net/archangel/atom?h=main 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:fd2ea796b20bcbebea19c43978fb08e3cd6754ed 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:d5c98ed92942192b169ebb74b560d5ed81848df0 - 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:d3d0e8ef4035b7a397ed623a97604679bfd00c47 - 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:sha1:124ccfabcf6a029d2c98fb22903b7f9576f459ee - 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:sha1:5d35df670a6780a12634e6f0ccbb918f53f355eb - 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:sha1:33ab3dba2cdba0c94f8dde7b421a2a2b0ec8dae3 - 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:sha1:9a9232aeed72e2d319418d06c790620db0db4ad2 - 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:c55ce46084635c188abb4516ba6ee6eee38dd11d - 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:ee457bb61c6bd974c2bf167fd45d9375d48c873a - 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:sha1:322cdf56dc984aed4da7166ccfa1990e09445b08 - 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.
