If `minio server /mnt/sd[abcd]1` and the occasional `apt-get upgrade` and changeover of DNS records is so much work, maybe you should just spend 100x for S3.
Seriously, there is a large amount of comments of people who seem terrified of this or throw out "but but updates and failing hardware". We run multi PB storage on prem at work and it's just fine. Not some massive team running it.
