This description is a repost of what was said about the project on the nix discourse

SkaraboxOS provides a flake template which combines:

• Creating a bootable ISO, installable on an USB key.
• nixos-anywhere to install NixOS headlessly.
• disko 1 to format the drives.
• deploy-rs 2 to deploy updates.

SkaraboxOS expects a particular hardware layout:

• 1 SSD or NVMe drive for the OS.
• 2 Hard drives that will store data. Capacity depends on the amount of data that will be stored. They will be formatted in Raid 1 (mirror) so each hard drive should have the same size.

WARNING: The 3 disks will be formatted and completely wiped out of data.

At the end of the process, the server will:

• Have an encrypted ZFS root partition using the NVMe drive, unlockable remotely through ssh.
• Have an encrypted ZFS data hard drives.
• Be accessible through ssh for administration and updates.
