Non-LUKS tests all pass: btrfs-single, btrfs-mirror, btrfs-stripe. 2026-01-25T08:50:51+00:00 Craig Jennings c@cjennings.net 2026-01-25T08:50:51+00:00 urn:sha1:1c68007534c25e2438f8d6ebaae8b3eff46fe5f3 - Add TODO for ISO naming convention change (date after project name) - Update session context with test results: - btrfs-single, btrfs-mirror, btrfs-stripe: PASS - btrfs-luks, btrfs-mirror-luks: reboot test blocked by passphrase prompt - Sync fix validated for non-encrypted btrfs 2026-01-24T19:00:09+00:00 Craig Jennings c@cjennings.net 2026-01-24T19:00:09+00:00 urn:sha1:1f7c72b67184e72c72de30814bebd7e0100cf1a3 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. 2026-01-24T11:24:59+00:00 Craig Jennings c@cjennings.net 2026-01-24T11:24:59+00:00 urn:sha1:2689dd341d9fcffe4d791d067244d3b018fb6248 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. 2026-01-24T04:57:21+00:00 Craig Jennings c@cjennings.net 2026-01-24T04:57:21+00:00 urn:sha1:e4ee55f9706d5567f45b6b4f6f007c09709fdfea - Create lib/btrfs.sh with full btrfs installation functions - Subvolume layout matching ZFS datasets (10 subvols) - Snapper configuration with timeline policy - GRUB + grub-btrfs for snapshot boot menu - Update disk.sh for filesystem-aware partition type - Update archangel with install_btrfs() path - Update build.sh to include lib/btrfs.sh - Update plan with Phase 2.7 (test) and 2.8 (LUKS) 2026-01-24T02:06:28+00:00 Craig Jennings c@cjennings.net 2026-01-24T02:06:28+00:00 urn:sha1:4560cbdc55e6bd5abe643806e4115d67313db564
