# Description: Implementation of the --no-overwrite-dir option was flawed in
|
|
# tar versions up to 1.32.90. This option is intended to preserve metadata
|
|
# of existing directories. In fact it worked only for non-empty directories.
|
|
# Moreover, if the actual directory was owned by the user tar runs as and the
|
|
# S_IWUSR bit was not set in its actual permissions, tar failed to create files
|
|
# in it.
