Hello! This is a news entry and it represents an
|
|
experimental new feature of Home Manager. The idea is to
|
|
inform you when something of importance happens in Home
|
|
Manager or its modules.
|
|
|
|
We will try to not disturb you about the same news more than
|
|
once so the next time you run
|
|
|
|
home-manager switch
|
|
|
|
or
|
|
|
|
home-manager build
|
|
|
|
it should not notify you about this text again.
|
|
|
|
News items may be conditional and will then only show if the
|
|
condition holds, for example if they are relevant to your
|
|
configuration.
|
|
|
|
If you want to see all relevant news then please use the
|
|
|
|
home-manager news
|
|
|
|
command.
|
|
|
|
Since this is an experimental feature any positive or
|
|
negative feedback would be greatly appreciated. For example,
|
|
by commenting in https://git.io/v5BJL.
|
|
'';
|
|
}
|
|
];
|
|
};
|
|
