| 21 | # The bug occurs when extracting from a tarfile a directory when the directory
|
|---|
| 22 | # already exists and the version in the tarfile has more permissive
|
|---|
| 23 | # permissions than your umask. In this case, the permissions of the
|
|---|
| 24 | # existing directory will toggle between the version which complies with
|
|---|
| 25 | # your umask (which would be correct, without -p) and the version from the
