S3 Strong Consistency required?

[hny-gd]

First of all @Barre thank you so much for this great innovation!

I have (unsuccessfully...) trying to find out if the underlying S3 implementation needs to support strong consistency for ZeroFS to work or if an S3 implementation like Garage (https://garagehq.deuxfleurs.fr/) can be used as well?

Thank you for the kind words!

You probably only need read-after-write guarantee, which garagehq offers.

Same for MinIO.
Ceph as well.

The CI uses MinIO for POSIX and ZFS on top of ZeroFS tests, so you should be fine with self hosted solutions.
