| 21 | # Description:
|
|---|
| 22 | # Restoring of directory modes and timestamps works correctly only
|
|---|
| 23 | # if the archive has normal member ordering, i.e. each directory
|
|---|
| 24 | # member is immediately followed by members located under that directory.
|
|---|
| 25 | # This is not true for incremental archives, where directory members
|
|---|
| 26 | # precede the non-directory ones. Due to this, GNU tar up to version 1.15.2
|
|---|
| 27 | # failed to correctly restore directory timestamps from an incremental
|
|---|
| 28 | # archive if this directory contained some files in it.
