This release has the following notable changes:
|
|
|
|
|
|
|
|
|
|
* The <<{opt-home-file-source}>> option now allows source files to be
|
|
|
|
|
hidden, that is, having a name starting with the `.` character. It
|
|
|
|
|
also allows the source file name to contain characters not typically
|
|
|
|
|
allowed for Nix store paths. For example, your configuration can now
|
|
|
|
|
contain things such as
|
|
|
|
|
+
|
|
|
|
|
[source,nix]
|
|
|
|
|
----
|
|
|
|
|
home.file."my file".source = ./. + "/file with spaces!";
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* The type used for the systemd unit options under
|
|
|
|
|
<<opt-systemd.user.services>>, <<opt-systemd.user.sockets>>, etc. has
|
|
|
|
|
been changed to offer more robust merging of configurations. If you
|
|
|
|
|
don't override values within systemd units then you are not affected
|
|
|
|
|
by this change. Unfortunately, if you do override unit values you may
|
|
|
|
|
encounter errors.
|
|
|
|
|
+
|
|
|
|
|
In particular, if you get an error saying that a ``unique option'' is
|
|
|
|
|
``defined multiple times'' then you need to use the
|
|
|
|
|
https://nixos.org/nixos/manual/#sec-option-definitions-setting-priorities[`mkForce`]
|
|
|
|
|
function. For example,
|
|
|
|
|
+
|
|
|
|
|
[source,nix]
|
|
|
|
|
----
|
|
|
|
|
systemd.user.services.foo.Service.ExecStart = "/foo/bar";
|
|
|
|
|
----
|
|
|
|
|
+
|
|
|
|
|
becomes
|
|
|
|
|
+
|
|
|
|
|
[source,nix]
|
|
|
|
|
----
|
|
|
|
|
systemd.user.services.foo.Service.ExecStart = lib.mkForce "/foo/bar";
|
|
|
|
|
----
|
|
|
|
|
+
|
|
|
|
|
We had to make this change because the old merging was causing too
|
|
|
|
|
many confusing situations for people.

=== State Version Changes
|
|
|
|
|
|
|
|
|
|
The state version in this release includes the changes below. These
|
|
|
|
|
changes are only active if the <<opt-home.stateVersion>> option is set
|
|
|
|
|
to ``19.03'' or later.
|
|
|
|
|
|
|
|
|
|
* There is now an option <<opt-programs.beets.enable>> that defaults
|
|
|
|
|
to `false`. Before the module would be active if the
|
|
|
|
|
<<opt-programs.beets.settings>> option was non-empty.
