…and technical details - Rewrite boot_zh.md with comprehensive technical details: - Add technical principles section (dm-verity, LUKS2, overlayfs) - Add volume structure with ASCII architecture diagram - Add boot modes section comparing GRUB and UKI modes - Add mermaid flowcharts for boot processes - Add auto disk expansion mechanism description - Add container runtime directory bindings - Add English translations: - Create README.md as English version of README_zh.md - Create docs/boot.md as English version of boot_zh.md - Update README_zh.md with workflow diagram and feature improvements
…age and adjust rw_overlay scope - Remove /data directory creation from encrypted system image - Adjust rw_overlay field behavior: instead of only deleting overlay directory, now resets the entire data volume when overlay type is disk (non-persistent) - Update logging in before_sysroot.rs to reflect the new data volume handling logic
Modify create-tarball target to include both staged and unstaged changes in the generated source tarball. This ensures the tarball reflects the current working state including: - Staged and unstaged modifications (via git diff + apply) - Untracked new files (via git ls-files + tar) This change is useful for preserving WIP changes when building from a dirty working tree.
… option Remove incorrect parameter placeholder from the help text of --rootfs-no-encryption option. This option is a flag that does not accept any value, but the help text incorrectly showed <rootfs_encrypt_passphrase> as its parameter.
…otfs Add support for dm-snapshot as an alternative to overlayfs for providing a writable root filesystem on top of dm-verity protected read-only rootfs. Key changes: - Add RwOverlayBackend enum with 'overlayfs' and 'dm-snapshot' variants - Rename RwOverlayType to RwOverlayLocation for clarity - Implement dm-snapshot device chain: dm-verity + dm-zero → dm-linear → dm-snapshot - Support both zram (ram) and LUKS2-encrypted data volume as COW devices - Add resize2fs call to expand filesystem after volume expansion - Update boot documentation (both EN and ZH) with new architecture details - Add udev rules to hide intermediate dm devices - Update configuration templates and examples The dm-snapshot backend provides block-level copy-on-write semantics without requiring overlayfs, eliminating the need for special handling of container runtime directories.

…nce-value examples Update documentation and README files to remove the deprecated --stage system flag from show-reference-value command examples. The --stage parameter is no longer required for this command.
Rename core concepts and configuration fields for clarity and consistency: - Volume Group: system -> cryptpilot - Data Volume: data -> delta (LVM logical volume name) - Device: /dev/mapper/data -> /dev/mapper/delta - Config section: [data] -> [delta] (with serde alias for backward compat) - Config field: rw_overlay_location -> delta_location (with serde alias) - Config field: rw_overlay_backend -> delta_backend - Type: DataConfig -> DeltaConfig - Type: RwOverlayLocation -> DeltaLocation - Type: RwOverlayBackend -> DeltaBackend Update all code references, documentation, and templates accordingly. Maintain backward compatibility through serde aliases for existing configurations. Signed-off-by: Kun Lai <laikun@linux.alibaba.com>
