Have you tried modifying the files for auto mount, here is a .md file i had gpt put together out of my notes. you can use the top section to use find/replace with your information to make it so you can copy and paste

# NFS Automount Setup for `sharenamefromNAS`
use find&replace for all instances on these items to match your setup to make reading easier:
IPAddress = your NAS ip
sharenamefromNAS = the share name from synology NFS settings (ie /volume1/Media)
volumes_NAME = the share name ie volumes_Media
volumes.NAME = the share name ie volumes_Media

This guide walks through the steps to configure an NFS mount on a Mac, ensuring it automounts on reboot.

## Prerequisites

- A Synology NAS with NFS enabled and the share `IPAddress:sharenamefromNAS`.
- A Mac with the correct permissions to access the NFS share.

## Steps

### 1. **Enable NFS on Synology NAS**
Ensure that NFS is enabled on the Synology and the correct permissions are set:

- Log into your Synology NAS and enable NFS under `Control Panel` > `File Services` > `NFS`.
- Configure the shared folder with the correct NFS permissions (e.g., `map all users to admin` for easy access).
  
### 2. **Modify `/etc/auto_master`**

This file controls the automounter master map.

1. Edit the `/etc/auto_master` file:

    ```bash
    sudo nano /etc/auto_master
    ```

2. Add the following line at the end of the file to reference the `auto_nfs` file:

    ```bash
    /-      auto_nfs
    ```

3. Save and exit (`Ctrl + O`, `Enter`, `Ctrl + X`).

### 3. **Create `/etc/auto_nfs`**

This file maps the NFS share to a local mount point.

1. Create or modify `/etc/auto_nfs`:

    ```bash
    sudo nano /etc/auto_nfs
    ```

2. Add the following line to map the share:

    ```bash
    sharenamefromNAS   -fstype=nfs,ro IPAddress:sharenamefromNAS
    ```

3. Save and exit (`Ctrl + O`, `Enter`, `Ctrl + X`).

### 4. **Ensure `sharenamefromNAS` Exists**

Automount relies on the directory being present before it can mount the NFS share. To ensure the directory exists at startup, we created a launch agent that runs at boot.

### 5. **Create Launch Agent to Create `sharenamefromNAS` Directory on Boot**

1. Create a new plist file for the launch agent:

    ```bash
    sudo nano /Library/LaunchDaemons/com.create.volumes.NAME.plist
    ```

2. Add the following content to the file:

    ```xml
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
      <dict>
        <key>Label</key>
        <string>com.create.volumes.NAME</string>
        <key>ProgramArguments</key>
        <array>
          <string>/bin/mkdir</string>
          <string>-p</string>
          <string>sharenamefromNAS</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>KeepAlive</key>
        <false/>
        <key>StandardErrorPath</key>
        <string>/tmp/create_volumes_NAME.err</string>
        <key>StandardOutPath</key>
        <string>/tmp/create_volumes_NAME.out</string>
      </dict>
    </plist>
    ```

3. Save and exit (`Ctrl + O`, `Enter`, `Ctrl + X`).

4. Load the launch agent:

    ```bash
    sudo launchctl load /Library/LaunchDaemons/com.create.volumes.NAME.plist
    ```

### 6. **Test the Setup**

1. To test the mount manually (before reboot):

    ```bash
    sudo automount -vc
    ```

2. Manually mount the NFS share if necessary:

    ```bash
    sudo mkdir -p sharenamefromNAS
    sudo mount -t nfs IPAddress:sharenamefromNAS sharenamefromNAS
    ```

3. Verify the files are accessible:

    ```bash
    ls sharenamefromNAS
    ```

### 7. **Reboot and Verify Automount**

After reboot, ensure the directory is created and the share is mounted automatically:

1. Reboot the system:

    ```bash
    sudo reboot
    ```

2. After reboot, verify the mount:

    ```bash
    ls sharenamefromNAS
    ```

3. Verify automount is working:

    ```bash
    mount | grep sharenamefromNAS
    ```

### Troubleshooting

- If the NFS mount is not showing after reboot, ensure that `sharenamefromNAS` exists by running `ls sharenamefromNAS`.
- If the directory is missing, check the launch agent logs located at `/tmp/create_volumes_NAME.out` for any errors.

---

This setup ensures that your NFS share from the Synology NAS is automatically mounted on `sharenamefromNAS` on the Mac after reboot, and the directory is created at boot if it does not exist.
