How would a bootstrap node itself be configured?

[TimDaub]

• The examples here and in js-libp2p always point out that e.g. an instance running online and hosted at port 4001 could be used as a bootstrap node.
• But that node running online being the bootstrap node, how is that supposed to be configured? For peerDiscover.tag.list does it have itself in there?

Actually, I found out myself: A bootstrap node doesn't integrate this package and neither defines any configuration as if it does, it'll start throwing errors like this one:
