Free up storage

[octvs]

Hey there,

Recently switched to 23.11 release to utilize terminal.colors but I've
noticed the storage usage is roughly doubled. The usual nix profile wipe-history and nix-store --gc doesn't seem to help, I can see many old
generations still with nix-on-droid generations.

Is there a provided method to free up some storage?

Cheers

nix-collect-garbage?

Unfortunately didn't change the situation. For context The storage used before was ~11GB, changing the flake input to `release-23.11` (and updating the `system.stateVersion` accordingly) ended me up at ~24GB.

Can you check for existing gcroots that may cause unneeded packages? See /nix/var/nix/gcroots

Sounds like you still have packages of the old nixpkgs version laying around.

Otherwise you could try and analyse the closure size of your current nix-on-droid generation.

Sadly this surpasses my newbie knowledge. Could you elaborate in case the above doesn't lead to anything?

You can run nix-collect-garbage -d to remove all unused packages. Have a look at nix-collect-garbage --help for more options.

Alright, my go-to was `nix-store --gc`, which I ran couple of times before asking this question. And it wasn't deleting pkgs from store anymore. For some reason (perhaps after killing the app or after removing the wakelock) now it started collecting garbage again, back to ~10GB. Cheers
