This change impacts the `SESSIONDIR` (container-run-time mount point) configuration, which is set to `$LOCALSTATEDIR/<apptainer or singularity>/mnt/session`. This detaches the packages from the top-level directory, rendering the NixOS module optional. + + The default behavior of the NixOS module `programs.singularity` stays unchanged. We add a new option `programs.singularity.enableExternalSysConfDir` (default to `true`) to specify whether to set the top-level `"/var/lib"` as `LOCALSTATEDIR` or not. + - DocBook option documentation is no longer supported, all module documentation now uses markdown. - `services.outline` can now be configured to use local filesystem storage instead of S3 storage using [services.outline.storage.storageType](#opt-services.outline.storage.storageType). diff --git a/nixos/modules/programs/singularity.nix b/nixos/modules/programs/singularity.nix index 05fdb4842c543..79695b29becae 100644 --- a/nixos/modules/programs/singularity.nix +++ b/nixos/modules/programs/singularity.nix @@ -45,6 +45,18 @@ in Use `lib.mkForce` to forcefully specify the overridden package.
