This behaviour is configurable by passing the `--arg withOnlyOffice false` flag to `nix-build` when building them.

## Updating the Deuxfleurs pinned nixpkgs
|
||||
The pinned sources files are generated with the [niv](https://github.com/nmattia/niv) tool.
|
||||
The pinned sources files are generated with the [npins](https://github.com/andir/npins) tool.
|
||||
|
||||
To update the pinned nixpkgs, you simply run the following command:
|
||||
|
||||
```shell
|
||||
niv update
|
||||
npins update
|
||||
```
|
||||
|
||||
To modify the pinned nixpkgs, you can use the `niv modify` command, for example, to move to nixpkgs-unstable:
|
||||
To modify the pinned nixpkgs, remove it and re-add it using the new target, for exemple for `nixos-unstable`:
|
||||
|
||||
```shell
|
||||
niv modify nixpkgs -b nixos-unstable
|
||||
npins remove nixpkgs
|
||||
npins add --name nixpkgs channel nixos-unstable
|
||||
```
|
||||
|
||||
## Quirks
|
||||
|
||||
- The CryptPad `package-lock.json` is included here because the upstream-provided one appeared to be desync'ed, so a
|
||||
manual lockfile generation was needed
