S3

I’ve hit this problem twice now. At MetaCPAN, we were looking at using S3 as a sync target for rsync from upstream CPAN — conceptually simple, except rsync wants a filesystem and S3 very much isn’t one. More recently, I wanted to mount an S3 bucket as an image cache for Buildah. Same wall. You end up writing glue code, or reaching for a FUSE driver that may or may not be production-ready, or just redesigning around the limitation.
