Bug reproduce instructions -------------------------- 1. Run `snapcraft --use-lxd` in one project 1. Move the project directory to another path 1. Re-run `snapcraft --use-lxd` Current behavior ----------------- Snapcraft errors with: ``` An error occurred with the instance when trying to start with 'LXD': Common start logic: Missing source '/home/brlin/工作空間/個人專案/Unofficial Snap Packaging for waifu2x' for disk 'snapcraft-project'. Ensure that 'LXD' is setup correctly and try again. ``` Expected behavior ------------------ Snapcraft should check the project directory path, and if it's changed, update the `snapcraft-project` disk source path
