The domain pkg.pacman.store offers pkgs for Pacman you can mount to access it as Pacman cache through your local IPFS daemon. All files accessed this way will be downloaded to your IPFS cache and shared with the network.

If you run on multiple machines in your local network IPFS will exchange the files locally rather than downloading the same file multiple times from the internet.

The data is hold and shared by a collaborative cluster, where everyone can participate.

If you want to join and contribute bandwidth and hard drive space, feel free to do so. The repo-size is about 70 GB. Since the data is rotating quite quickly it's recommended to enable the Garbage Collector with --enable-gc for your IPFS-Daemon.

The default storage size for IPFS needs to be altered in the config file.

If you're running your cluster follower on a computer with a static ip or a static domain name: Feel free to add it to the list of peer_addresses in the JSON config files, found in collab-cluster-config. Then send a pull request.

Details how to join the cluster are available on the collab cluster website.

tl;dr: You need a locally running IPFS node. Your IPFS StorageMax setting may needs to be adjusted. You need ipfs-cluster-follow, then run:

ipfs-cluster-follow pacman.store run --init cluster.pacman.store

Install ipfs on each of your systems, you need set it up and and start it as a service.

Then add the following to your /etc/pacman.d/mirrorlist as first entry:

# IPFS
Server = http:https://127.0.0.1:8080/ipns/pkg.pacman.store/arch/$arch/default/$repo

Since directory lookups may be slower over IPNS, you may need to set the pacman option --disable-download-timeout for fetching dbs or packages.

ISO and bootstrap files are also stored on the cluster:
