Other than being generally unexpected (to me), it has the practical implication that on a system running tmpwatch/tmpreaper, things untarred by bsdtar don't survive for long. Unless the archive preserves access time and bsdtar is asked to preserve it (I don't believe this is supported however?), I would expect the access time to remain untouched, or at least set to >= creation time. >How-To-Repeat: % ls -l total 0 % touch testfile % stat -x testfile File: "testfile" Size: 0 FileType: Regular File Mode: (0644/-rw-r--r--) Uid: ( 1001/ scode) Gid: ( 0/ wheel) Device: 98,4164878385 Inode: 1424746 Links: 1 Access: Tue Jun 24 00:20:59 2008 Modify: Tue Jun 24 00:20:59 2008 Change: Tue Jun 24 00:20:59 2008 % tar -cf testfile.tar testfile % tar -xf testfile.tar % stat -x testfile File: "testfile" Size: 0 FileType: Regular File Mode: (0644/-rw-r--r--) Uid: ( 1001/ scode) Gid: ( 0/ wheel) Device: 98,4164878385 Inode: 1424748 Links: 1 Access: Thu Jan 1 01:00:00 1970 Modify: Tue Jun 24 00:20:59 2008 Change: Tue Jun 24 00:21:18 2008 >Fix: No patch.
