* [system-manager](https://github.com/numtide/system-manager) addresses the
limitation of NixOS to use systemd units independently and can deploy many
services in the NixOS repository on any Ubuntu-based distribution.

Aside from the first option, the biggest drawback is that these solutions are
not generic and there is only little reuse possible between service
* [devenv](https://devenv.sh) also makes it possible to run multiple processes
(of different services) in a Nix-based development environment. It works a

* [nixos-init-freedom](https://git.sr.ht/~guido/nixos-init-freedom) puts some efforts on replacing systemd-as-pid-1 with s6. Instead of implementing a generic service layer, it translates parts of systemd module configuration into s6 configuration.

Aside from the first and last option, the biggest drawback is that these

Why not group the "best options" and say "Aside from the last two options..."?

solutions are not generic and there is only little reuse possible between service
configurations.
