The NFS is then mounted as the lower directory of an overlayfs, $directory_workdir is mounted as the workdir, and $directory_cow is mounted as the upper directory. However, as of recent, the customer can not edit any data unless the necessary files are 'touch'ed first (or if you use vim, force-written). "uname -a" returns "Linux <shortname> 4.4.0-104-generic #127-Ubuntu SMP Mon Dec 11 12:16:42 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux".
