Note that the database is strongly-typed so you need to use the same types
as described in the GSettings schema. For example, if an option is of type
<literal>uint32</literal> (<literal>u</literal>), you need to wrap the number
using the <literal>lib.hm.gvariant.mkUint32</literal> constructor.
Otherwise, since Nix integers are implicitly coerced to <literal>int32</literal>
(<literal>i</literal>), it would get stored in the database as such, and GSettings
might be confused when loading the setting.

to convert dconf database dumps into compatible Nix expression.
