A set of shell script fragments that are executed when a NixOS
|
|
system configuration is activated. Examples are updating
|
|
/etc, creating accounts, and so on. Since these are executed
|
|
every time you boot the system or run
|
|
<command>nixos-rebuild</command>, it's important that they are
|
|
idempotent and fast.
