Add "After=autofs.target" to the section of your file. Instead, we need to wait for autofs to come up. However, this does not work with filesystems mounted by autofs (at least, it didn't for me). ![]() Many guides will tell you to add the "After=remote-fs.target" or "After=home.mount" or "RequiresMountsFor=/home". The next issue we run into is that vncserver isn't waiting for our NFS mount. ![]() Install the new SELinux policy: "semodule -X 300 -i vncsession.pp".Tell SELinux that we're using NFS home directories by running "setsebool -P use_nfs_home_dirs on".Generate the new SELinux policy file (vncserver.pp) by running "make vncserver.pp".Obtain and extract the tigervnc v1.12 sources.If that isn't available for the OS, we can just pull the new SELinux configuration from upstream and install it on our system. This has been fixed upstream in tigervnc v1.12. So first we need to allow vncserver access to NFS home directories. It turns out that at least up to NFSv4.1, NFS does not have full support for SELinux contexts you can only set the context per-mount, not per-file/directory.
