- // Whiteouts are files with a special meaning for the layered filesystem.
- // Docker uses AUFS whiteout files inside exported archives. In other
- // filesystems these files are generated/handled on tar creation/extraction.
- // WhiteoutPrefix prefix means file is a whiteout. If this is followed by a
- // filename this means that file has been removed from the base layer.

- // WhiteoutMetaPrefix prefix means whiteout has a special meaning and is not
- // for removing an actual file. Normally these files are excluded from exported
- // archives.
- const WhiteoutMetaPrefix = WhiteoutPrefix + WhiteoutPrefix
- // WhiteoutLinkDir is a directory AUFS uses for storing hardlink links to other
- // layers. Normally these should not go into exported archives and all changed
- // hardlinks should be copied to the top layer.

- // WhiteoutOpaqueDir file means directory has been made opaque - meaning
- // readdir calls to this directory do not follow to lower layers.
