Failed to mount tmpfs at /run: operation not permitted

Explanation:

When you see the error message “failed to mount tmpfs at /run: operation not permitted” it means that the system is unable to mount the tmpfs filesystem on the specified mount point due to insufficient permissions.

The tmpfs filesystem is a common type of virtual memory filesystem used by Linux to store temporary files. It is typically mounted on the /run directory, which is a temporary filesystem created during system startup.

There are a few possible reasons why you may encounter this error:

1. Insufficient Privileges: The process trying to mount the tmpfs filesystem may not have the necessary privileges to perform the operation. Mount operations usually require root or superuser privileges.
2. Filesystem Not Supported: The system may not have support for the tmpfs filesystem. This is highly unlikely as tmpfs is commonly used in modern Linux distributions.
3. Mount Point Already Used: Another filesystem or device may already be mounted on the specified mount point (/run).

To resolve this issue, you can try the following solutions:

1. Run as Root: If the process trying to mount tmpfs does not have sufficient privileges, you can try running the command as root or using the sudo command. For example, if you are using the mount command, use the following syntax:

        sudo mount -t tmpfs tmpfs /run
    

2. Check Filesystem Support: Verify that your system supports the tmpfs filesystem. You can do this by checking the kernel configuration or consulting the documentation for your specific Linux distribution.
3. Verify Existing Mount Points: Use the mount command to check if another filesystem or device is already mounted on the /run directory. If so, you may need to unmount it before attempting to mount the tmpfs filesystem. Use the following command to list all mounted filesystems:

        mount
