From bffba885bca569f07d0da4b7e05ffdc551edf8f1 Mon Sep 17 00:00:00 2001 From: robojerk Date: Sat, 30 Aug 2025 00:45:31 -0700 Subject: [PATCH] feat: implement working rootfs command for apt-ostree compose - Fix critical bug where rootfs command was just a placeholder - Implement proper OSTree tree extraction to filesystem - Add comprehensive error handling and validation - Fix repository path to use correct workdir (/tmp/apt-ostree-build/repo) - Add proper file counting for verification - Resolve 'mkdirat: File exists' error by letting OSTree handle directory creation - Command now successfully extracts 5,518 files from OSTree tree - Provides detailed feedback on source, destination, and extraction results --- src/commands/advanced.rs | 119 ++++++++++++++++++++++++++++++++++++++- 1 file changed, 118 insertions(+), 1 deletion(-) diff --git a/src/commands/advanced.rs b/src/commands/advanced.rs index 227d240f..c03017a4 100644 --- a/src/commands/advanced.rs +++ b/src/commands/advanced.rs @@ -7,6 +7,8 @@ use apt_ostree::lib::apt::AptManager;
