# FUTURE SERVER
One day, I would like to move off of Yunohost and do this all by myself.
Steps I would need to take.
1. Backup Data
- all data is on ZFS mirrors, no action needed
- other configuration not important
2. Install NixOS
- install with zfs-on-root, encryption enabled
3. Import ZFS Pools
- /mnt/hermes
4. Install Reverse proxy
- caddy-dns-gandi on github
5. Setup services
- user docker or nixos services
- tailscale
- calibre-web
- jellyfin
- immich-photos
- nextcloud (*!)
- whoogle
6. Setup Backups
- zfs mirror pool (name?)
# Other Considerations
- where to setup docker stuff?

# NixOS - Knossos
My test system.
## Goals
- Learn NixOS.
- Attempt to make basic media homelab, a la [Yunohost](https://yunohost.org/)[^1]...but declarative, reproducable
- Try to avoid Docker
- No flakes
## Tasks
- [X] ZFS for root file system
- [X] Tailscale
- [X] VPS Caddy reverse proxy --> NixOS machine
- [X] Setup Jellyfin
- [X] Setup calibre-web
- [X] Setup Transmission
- [ ] Setup Nextcloud
- [ ] Setup systemwide auth system - LDAP? OAuth? OR don't do this

## Future Checklist when Moving to New Server
When I do eventually make a new server, or this server needs a whole reinstall. What steps will I need to do?
[Future Server Checklist](FUTURE-SERVER.md)
[^1]: No shade on [Yunohost](https://yunohost.org/). It's a great project and got me into self-hosting. I just want to see if I can spread my wings and fly. Setting up a new Debian server from scratch is kinda annoying. I'd rather not do that again.
