-xnet
-====
-
-Base configuration for any machines running a standard xnet
-configuration.
-
-Notable features:
-
- - Root filesystem running in RAM
- - Automated ZFS partitioning of disk
- - Hardened SSH and web services
-
-Usage
-=====
-
-The entire module is exposed from the top-level flake as a nixosModule,
-but it changes too often to be considered stable. Options are made
-available when imported under the 'xnet' attribute set.
