Re: [Astlinux-users] What is .wh.__dir_opaque

[Lonnie A. <li...@lo...>]

Hi Michael,

AstLinux version 1.3.8 and older used a unionfs driver (kernel based) that used "whiteout" files added to the filesystem (ex. .wh.__dir_opaque) to note added/removed directories, among other things.

AstLinux version 1.3.10 and newer uses a different unionfs driver (FUSE based), so the old whiteout files (ex. .wh.__dir_opaque) are no longer used/needed.

These whiteout files are of zero size, so the simplest is to ignore them.  If you want to remove the old whiteout files, you can.
