I’m doing this using transmission-daemon
First, create the torrent and add it to transmission as normal.
Then, go to /var/lib/transmission/downloads
and run ipfs add -r TorrentFolder
Finally, rm -r TorrentFolder
and ln -s /ipfs/<CID>
Performance isn’t amazing due to limitations in the current FUSE implementation, but it works and now my content is on both IPFS and BitTorrent!
