Hi. I have a debian ftp server with aufs. A some time ago I started to note that some directories renaming make strange things. For example, if we have a one directory on many branches (all are rw) and rename it, we get a new name in aufs, but in branches we get a directory with old name and same stuff in it and a directory with a new name.
What it can be?
