Since lib.mdDoc is already defined as just id, this commit is a no-op as far as Nix (and the built manual) is concerned.

Whether to add the activation script to the system profile.
|
|
|
|
The default, to have the script available all the time, is what we normally
|
|
do, but for image based systems, this may not be needed or not be desirable.

Like `system.systemBuilderCommands`, but only for the commands that are
|
|
needed *both* when the system is activatable and when it isn't.

Disclaimer: This option might go away in the future. It might be
|
|
superseded by separating switch-to-configuration into a separate script
|
|
which will make this option superfluous. See

https://github.com/NixOS/nixpkgs/pull/263462#discussion_r1373104845 for

a discussion.

A separate activation script package that's not part of the system profile.
|
|
|
|
This is useful for configurations where `system.activatable` is `false`.
|
|
Otherwise, you can just use `system.build.toplevel`.
