From fa22f3f903931f9ef10fe4b29fdebae3be276fd9 Mon Sep 17 00:00:00 2001 From: robojerk Date: Wed, 10 Sep 2025 11:35:49 -0700 Subject: [PATCH 1/2] Add enhanced partitioning system with multiple tool support - Add --partitioner option supporting parted, sgdisk, sfdisk, auto - Implement fallback mechanism when tools fail - Add robust partition verification and validation - Improve error handling and logging - Add loop device management with retry logic - Support different partition size units (kB, MB, MiB) - Integrate partitioning approaches from partition_creator.rs Features: - Auto-selection tries parted -> sgdisk -> sfdisk - User can force specific tool with --partitioner - Graceful fallback for unknown tools - Detailed logging of which tool is used - Proper resource cleanup and error recovery --- src/main.rs | 997 ++++++++++++++++++++++++++++++++++++++++++++++------ todo.txt | 137 ++++++++ 2 files changed, 1028 insertions(+), 106 deletions(-) create mode 100644 todo.txt diff --git a/src/main.rs b/src/main.rs index c429e08..d5e3417 100644 --- a/src/main.rs +++ b/src/main.rs @@ -37,10 +37,11 @@ use clap::Parser;
