Hello William,

Let me make sure.
Are you using _plain_ aufs 20090126?

Show your operation in detail. Which attribute was not updated?
For example,
# mount -t aufs -o br:/rw:/ro none /au
$ ls -l /au
:::
-rw-r--r-- 1 userA groupA 1382 Oct 27 17:57 fileA
:::
$ echo abc >> /au/fileA
$ ls -l /au
-rw-r--r-- 1 userA groupA 1382 Oct 27 17:57 fileA
The timestamp and size of fileA is unchanged.
Something like this?
