Well, uBlue can be as light as you want it to be.
Some other projects I’m thinking of:
- VanillaOS (Debian based)
- NixOS
- Fedora CoreOS
- uCore (based on CoreOS)
- openSUSE MicroOS
- EndlessOS (Debian based)
- blendOS
Is it for a personal computer or a server?
Maybe try installing trough a package manager like Winget or Chocolatey
