View Source 
const WhiteoutLinkDir = WhiteoutMetaPrefix + "plnk"

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.

View Source 
const WhiteoutMetaPrefix = WhiteoutPrefix + WhiteoutPrefix

WhiteoutMetaPrefix prefix means whiteout has a special meaning and is not for removing an actual file. Normally these files are excluded from exported archives.

View Source 
const WhiteoutOpaqueDir = WhiteoutMetaPrefix + ".opq"

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

View Source 
const WhiteoutPrefix = ".wh."

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.
