Type of Change

  • Bug fix
  • New feature
  • Breaking change
  • Documentation update

Motivation and Context

container stores sparse disk images under ~/Library/Application Support/com.apple.container. Their apparent size can look enormous in Finder and can stall or inflate Time Machine backups. Maintainers asked for FAQ / known-issue docs covering the sparse-file explanation and excluding that directory from Time Machine.

Fixes #497

Testing

  • Tested locally
  • Added/updated tests
  • Added/updated docs

Docs-only change: added docs/faq.md and linked it from the README.

Document that container disk images are sparse files whose apparent
size can confuse Finder and Time Machine, and show how to exclude
~/Library/Application Support/com.apple.container from backups.

Fixes apple#497
