### Agenda

- [andrewrynhard] Should an implementation live in the COSI org?
- We feel that having a reference implementation is good.
- We should design such that multiple implementations is easy.
- We should get clear about the name of the spaces (e.g. engine).
- names should be inclusive of new tools and old tools
- EG: the launcher/bootstrap component should include:
- systemd
- init
- engine
- windows init
- osx launcher
- freebsd init
- [andrewrynhard] Branding.
- Create cosi.dev repo.
- andrew give nóva access to repo
- we need a youtube channel?
- nóva to set up hello world
- [andrewrynhard] Git LFS?
- yes
- [andrewrynhard] Equinix Metal stream.
- We need to get onto meetups, steams, etc. to start evangelizing COSI.
- [nóva] First draft at charter
- thoughts reviews?
- [repo here](https://github.com/cosi-project/community/pull/5)
- White [paper google doc](https://docs.google.com/document/d/1dt_XKC8uOBi82a-SYXxcs_KMJKtyH-h7FuzbgBhwIoE/edit)?
- [invidian] Initial spec compatibility between different OSes
- https://github.com/cosi-project/specification/pull/1#discussion_r613611966
- @andrewrynhard will write a vision statement.

### Agenda

- Questions/Answers
-
- [nóva] Intros
-
- [nóva] can we collect problem statements?
- [distributed operating system void](https://nivenly.com/lib/2021-04-02-operating-system-interface/)
- [andrew] is anyone willing to share today?
- [stefan] everyone is solving the underlying OS problem in different ways
- drivers, specs, storage
- if we are able to achieve a spec, that would be a good thing
- this is very ambitious, but we should start
- [mateusz] kubelet
- having a clearly defined way of kubernetes interfacing with the operating systems
- having a clear API should make everyones lives easier
- [christian]
- we are running rook/ceph ("bad things")
- running flatcar
- we do an update here -> trouble over there
- hopefully COSI will help with standardizing this
- CNI seems like an anti pattern (installing after)
- [stefan] standard CNI
- See cilium, BGP networking
- Why is there so many choices to achieve the same goal
- There might be some work around the kubelet
- [nóva] kubelet
- drop in, replace, alternative to kubelet
- maybe something there
- kubelet seems like "main interface"
- maybe we just have kubelet features?
- [stefan] where does kubernetes end?
- where does kubelet start?
- where does cluster API end
- [andrew] there seems to be overlap between kubelet/cosi - we need to define these things
- kubelet is critical part of cosi
- [nóva] cni, cri, csi
- all took a top down approach to solving compute, storage, networking
- [seán] API
- really the API is the value here
- having a standardized interface
- the exercise is abstracting or "presenting" the operating system (kernel) to the commonly used configuration
- [stefan] dat systemd tho
- [seán] systemd and kubernetes dont really conflict
- systemd and kubernetes are the same thing but at different layers
- [nóva] systemd and kubernetes might be the same thing just with a different scope
- [andrew] does systemd share the goal of kubernetes
- talos is a reimaginement of distributed OS
- [andrew] there is a COSI spec
- systemd can have a shim
- system can implement COSI spec
- talos also has it
- assumption that you can SSH into box and mutate system via systemd and package managers
- ain't nobody got time for that
- [christian]
- Q: is cosi k8s centric?
- A: the interface is for all distributed systems
- [steven]
- post kubernetes world where "nodes" can communicate with each other
- see below "history of COSI"
- [nóva] should we agree on "the interface"?
- distributed vs non-distributed
- a "set" can go 0:1:N
- [seán] this is an interface to a kernel?
- [nóva] we could just add a new syscall as a thought experiment
- sounds like we agree on the implementation
- distributed interface from 0:N
- History of COSI:
- [Talos](https://github.com/talos-systems/talos)
- [@andrewrynhard tweet](https://twitter.com/andrewrynhard/status/1294063909008052224)
