configurations to a User.

This is useful when you wish for a Host to provide a common
22
-
_home environment_ for all its users, or for a User to require
23
-
common _os environment_ everywhere it is defined.

Only when you wish for a Host-aspect to provide common _home settings_
23
+
(`homeManager`, etc) for **all** its users.
24
+
25
+
And even then there are much simpler and better ways:
26
+
27
+
```nix
28
+
# an aspect with all common stuff for everybody
29
+
den.aspects.user-base = { nixos = ...; homeManager = ...; hjem = ...; };
30
+
31
+
# include it in all users
32
+
den.ctx.user.includes = [ den.aspects.user-base ];
33
+
```

There are at least two (built-in) ways to achieve this in Den.

The `den._.bidirectional` and `den._.mutual-provider`, the

The `den._.bidirectional` and `den._.mutual-provider` batteries. The
27

first one was extracted from den-core and the second started
28

life as an **aspect routing** example, but made it to become
29

proper battery itself and even safer to use.
