I need to automate garbage collection process on my server, so I need to run nix-collect-garbage -d
declaratively. I can create systemd service that does that, but I wanted to clarify, if there’s any native methods of declarative management available?
There is the nix.gc.*
configuration option, which should be exactly what you want. You may also be interested in nix.optimise
and nix.autoOptimiseStore
.

What’s the difference between autoOptimiseStore
and optimise.*
.
Do they refer to different kinds of optimisations?
The option comments are not clear on this.
nix.autoOptimise
does optimise on each operation to the store.
The nix.optimise.*
configure a scheduled service that basically runs nix optimise-store
occasionally.
