The Perl implementation of switch-to-configuration will be deprecated
and removed in the 25.05 release of NixOS. Please migrate to the
newer implementation by removing `system.switch.enableNg = false`
from your configuration. If you are unable to migrate due to any
issues with the new implementation, please create an issue and tag
the maintainers of `switch-to-configuration-ng`.
