- Created a `limits` module to centralize system limit configurations.
- Replaced inlined user and systemd limits with the new module on aarch64 and x86_64 platforms.
- Simplifies maintenance and ensures consistency across configurations.
Commented out DNSSEC configuration and single-label resolution in systemd-resolved. This change disables custom DNS behavior to potentially align with default system behavior or compatibility requirements.
Introduced hardware and system configurations for the aarch64 NixOS system. Includes hardware setup, base system packages, and enabling key services such as Docker and Podman. This establishes the foundation for managing ARM-based systems.
