Sure, the steps are different depending on which i2p router you are using, for i2pd, you just have to add a file in your tunnels.d directory, or add an entry in your tunnels.conf and then reload the tunnel configuration. In Java i2p, you will have to do it through the gui.
Here is the link to the tunnel config for i2pd: http://i2pcraft.i2p/example/i2pdtunnel.html And here is a link to a screenshot of Java i2p: http://i2pcraft.i2p/img/config.png
The tunnel length can be reduced to 1 for better performance, but you will sacrifice some anonymity.
But once the tunnel is setup and running, you can use Minecraft 1.19.2, or a newer version with ViaFabricPlus and connect to 127.0.0.1:25565. Its an anarchy server, but its pretty chill, I heard there is an iron farm and trained villagers for anyone to use near spawn, but I havent seen them. It is a cracked server, so you will have to use /register and save your password somewhere.
The other server is at mc.r4sas.i2p, I couldnt copy any links from there, I think its down rn, but the instructions for i2pcraft should be pretty much the same, just a different address. But I think its a russian speaking server, all of the players ive seen on i2pcraft speak english.
I dont think systemd will expand the
~, try replacing theExecStart=/bin/bash ~/.local/bin/ocamlfuseStartup.shline withExecStart=/bin/bash %h/.local/bin/ocamlfuseStartup.sh, this will expand to your home directory, if its still giving a not found error, try runningwhich google-drive-ocamlfusein a terminal and make sure the path is correct
