Hi Andrew, For autofs maps that recursively reference other map entries in their mount point path we need to ensure that these mounts are performed prior to the current mount request being done. We've used the access system call, made just prior to performing the mount, to make this happen. In the case of bind mounts, however, the lookup flags in the path walk don't trigger a mount. To do this we need to also trigger a mount when we see the LOOKUP_ACCESS flag.
