        For safety, we're going to assume you're running on a server, or other setup where you're directly connected to the internet / there is no LAN,
        thus we're going to use the server profile, to prevent IPFS from scanning private subnets to find hosts on the LAN.

        Going to run the following command:

            su -c \"bash -c 'IPFS_PATH="${IPFS_PATH}" ipfs init --profile server'\" ipfs

        If you ARE on a private LAN and not connected directly to the internet (i.e. a computer on a personal home network),
        then you may re-enable private subnet scanning / MDNS discovery by running the command:
            
            su -c \"bash -c 'IPFS_PATH="${IPFS_PATH}" ipfs config profile apply local-discovery\" ipfs
            systemctl restart ipfs

        (If you're using a server provided by a hosting company such as Privex, DigitalOcean, Linode, Hetzner, Google Cloud etc.,
         do NOT enable local-discovery without first contacting your hosting company and confirming that both running IPFS is allowed,
         and that their firewalls won't freak out over IPFS scanning private subnets such as 192.168.0.0/16 and 10.0.0.0/8)
