Enable temporary file storage on tmpfs and configure TMPDIR for the nix-daemon. Also, ensure temporary files are cleaned on boot and enable fstrim service for filesystem maintenance.
The default value for `wheelNeedsPassword` has been changed to `true` in `base/default.nix`. The redundant entry in `gui/default.nix` setting `wheelNeedsPassword` to `true` was removed as it is now enforced by the base module.
The update modifies the default setting for the 'sudo wheelNeedsPassword' option in both the base and gui modules/services. Now, the base service has 'sudo wheelNeedsPassword' marked as a default option and disabled by default in the gui service.
This commit removes the "--refresh" flag from the system.autoUpgrade field in the default.nix file. The update function will now rely on the remaining flags only.
The primary change in this commit enables the Git program in the base/default service module. This marks a configuration alteration at the systems level, transferring the 'programs.git.enable' declaration from 'systems/x86_64-linux/mx/default.nix' to 'modules/nixos/services/base/default.nix'. We've undertaken this change for better structuring of our service configuration.
This commit moves the kernel package version override from the base nixos service to specific system configurations. Now, the latest linux packages will be used only in the system configurations where the override has been explicitly added. This approach gives us more flexibility to handle different kernel package versions for different systems.
