Due to this, GNU tar up to version 1.15.2 # failed to correctly restore directory timestamps from an incremental # archive if this directory contained some files in it. # # References: <200511291228.47081.karaman@dssgmbh.de> AT_SETUP([restoring timestamps from incremental]) AT_KEYWORDS([incremental timestamp restore incr02]) AT_TAR_CHECK([ # Create directory structure mkdir dir mkdir dir/subdir1 mkdir dir/subdir2 genfile --length 10 --file dir/subdir1/file # Save mtime for later comparison genfile --stat=mtime dir/subdir1 > ts # Create an archive.
