Completely exclude mpoints when running rsync
We used to exclude mount point from rsync with options like this: --exclude mount/point/* This will copy the directory and leave out all files under it. In some cases, this causes problems because rsync will fail if it cannot stat the directory and some mount point will only return stat info to their owner and not root. Even if this wasn't the case, we cannot determine the real directory attributes. The stat syscall will return the attributes associated with the mount options. It's better to completely exclude those mpoints in rsync and create them explicitly after the command runs. We make them inherit the mode and the ownership of their parent directory.
