> just not gone use anything with BTRFS. Why? (Legitimately asking, I haven't played around much with using different filesystems.)

Not the OP, but I used btrfs till a couple of years ago for my root partition. Because of the nature of snapshots, the partition gradually fills up after big system updates. The usual `df` command is inaccurate with btrfs. Instead there's a set of btrfs specific tooling that you need to learn which can show the actual space in use. Freeing up unused space from older snapshots also requires manual work. I often had to…

Same thing happens with ZFS to be fair.

I used to work for Suse. During my time there MicroOS was broadly considered to be a joke and abandonware by my coworkers. I worked on the very team developing their k8s solution ( the entire team of which was fired due to the recent acquisition )

My recommendation, which is, of course, my personal opinion, is to stay away from MicroOS.

You're most probably right. I run my system on a 20gb btrfs partition and I have run into issues before where I ran out of space because of one big binary file that was in every snapshot.

That shouldn't be an issue. Btrfs snapshots are copy-on-write, so unless all blocks changed the big binary file should be there just once.

Yeah.. It happened to be a qcow2 image for a virtual machine. I meant to put it on another disk but accidentally forgot to set the right path.

This sounds neat, but the system requirements seem a little odd. Minimum 20 GB of disk space for a stripped down Linux distro?

Well..that's been addressed now: https://kubic.opensuse.org/blog/2020-11-23-requirements/

JeOS it's a striped down version of a full blown linux bistro. Think Like RH,Centos. Can be used as a VM os or for anything else. MicroOS it's a cloud OS linux, more like: CoreOS, RancherOS, AtomicOS. I think it's a default choose for Kubernetes environments. I've been using JeOS for k8s hosts of Rancher environments since RancherOS was deprecated and I'm glad that they finally released a cloud OS like MicroOS. In ca…

So it's for Kubernetes nodes, VMs and bare metal?

yup
