More importantly, can it be turned off? In particular, this is yet another way that the following two commands seem to differ, even though (by my understanding), they should be exactly interchangable: chmod u=rw file setfacl -m user::rw- file The second changes the mtime, the first does not. The second does not work on all filesystems, the first does. The ACL routines I wrote for bsdtar (long story why this was necessary...) are careful to convert changes to basic ACL entries (such as the second example above) to the equivalent chmod. It seems to me that the library/kernel acl routines should also behave this way? Tim
