Release 16.03 (“Emu”, 2016/03/31)
In addition to numerous new and upgraded packages, this release has the
following highlights:
Systemd 229, bringing
numerous
improvements over 217.
Linux 4.4 (was 3.18).
GCC 5.3 (was 4.9). Note that GCC 5
changes
the C++ ABI in an incompatible way; this may cause problems if you
try to link objects compiled with different versions of GCC.
Glibc 2.23 (was 2.21).
Binutils 2.26 (was 2.23.1). See #909
Improved support for ensuring
bitwise
reproducible builds. For example, stdenv now sets
the environment variable
SOURCE_DATE_EPOCH
to a deterministic value, and Nix has
gained
an option to repeat a build a number of times to test determinism.
An ongoing project, the goal of exact reproducibility is to allow binaries
to be verified independently (e.g., a user might only trust binaries that
appear in three independent binary caches).
Perl 5.22.
The following new services were added since the last release:
services/monitoring/longview.nixhardware/video/webcam/facetimehd.nixi18n/input-method/default.nixi18n/input-method/fcitx.nixi18n/input-method/ibus.nixi18n/input-method/nabi.nixi18n/input-method/uim.nixprograms/fish.nixsecurity/acme.nixsecurity/audit.nixsecurity/oath.nixservices/hardware/irqbalance.nixservices/mail/dspam.nixservices/mail/opendkim.nixservices/mail/postsrsd.nixservices/mail/rspamd.nixservices/mail/rmilter.nixservices/misc/autofs.nixservices/misc/bepasty.nixservices/misc/calibre-server.nixservices/misc/cfdyndns.nixservices/misc/gammu-smsd.nixservices/misc/mathics.nixservices/misc/matrix-synapse.nixservices/misc/octoprint.nixservices/monitoring/hdaps.nixservices/monitoring/heapster.nixservices/monitoring/longview.nixservices/network-filesystems/netatalk.nixservices/network-filesystems/xtreemfs.nixservices/networking/autossh.nixservices/networking/dnschain.nixservices/networking/gale.nixservices/networking/miniupnpd.nixservices/networking/namecoind.nixservices/networking/ostinato.nixservices/networking/pdnsd.nixservices/networking/shairport-sync.nixservices/networking/supplicant.nixservices/search/kibana.nixservices/security/haka.nixservices/security/physlock.nixservices/web-apps/pump.io.nixservices/x11/hardware/libinput.nixservices/x11/window-managers/windowlab.nixsystem/boot/initrd-network.nixsystem/boot/initrd-ssh.nixsystem/boot/loader/loader.nixsystem/boot/networkd.nixsystem/boot/resolved.nixvirtualisation/lxd.nixvirtualisation/rkt.nix
When upgrading from a previous release, please be aware of the following
incompatible changes:
We no longer produce graphical ISO images and VirtualBox images for
i686-linux. A minimal ISO image is still provided.
Firefox and similar browsers are now wrapped by
default. The package and attribute names are plain
firefox or midori, etc.
Backward-compatibility attributes were set up, but note that
nix-env -u will not update your
current firefox-with-plugins; you have to uninstall it
and install firefox instead.
wmiiSnap has been replaced with
wmii_hg, but
services.xserver.windowManager.wmii.enable has been
updated respectively so this only affects you if you have explicitly
installed wmiiSnap.
jobs NixOS option has been removed. It served as
compatibility layer between Upstart jobs and SystemD services. All services
have been rewritten to use systemd.serviceswmiimenu is removed, as it has been removed by the
developers upstream. Use wimenu from the
wmii-hg package.
Gitit is no longer automatically added to the module list in NixOS and as
such there will not be any manual entries for it. You will need to add an
import statement to your NixOS configuration in order to use it, e.g.
];
}
]]>
will include the Gitit service configuration options.
nginx does not accept flags for enabling and disabling
modules anymore. Instead it accepts modules argument,
which is a list of modules to be built in. All modules now reside in
nginxModules set. Example configuration:
s3sync is removed, as it hasn't been developed by
upstream for 4 years and only runs with ruby 1.8. For an actively-developer
alternative look at tarsnap and others.
ruby_1_8 has been removed as it's not supported from
upstream anymore and probably contains security issues.
tidy-html5 package is removed. Upstream only provided
(lib)tidy5 during development, and now they went back to
(lib)tidy to work as a drop-in replacement of the
original package that has been unmaintained for years. You can (still) use
the html-tidy package, which got updated to a stable
release from this new upstream.
extraDeviceOptions argument is removed from
bumblebee package. Instead there are now two separate
arguments: extraNvidiaDeviceOptions and
extraNouveauDeviceOptions for setting extra X11 options
for nvidia and nouveau drivers, respectively.
The Ctrl+Alt+Backspace key combination no longer kills
the X server by default. There's a new option
allowing to enable
the combination again.
emacsPackagesNg now contains all packages from the ELPA,
MELPA, and MELPA Stable repositories.
Data directory for Postfix MTA server is moved from
/var/postfix to /var/lib/postfix.
Old configurations are migrated automatically.
service.postfix module has also received many
improvements, such as correct directories' access rights, new
aliasFiles and mapFiles options and
more.
Filesystem options should now be configured as a list of strings, not a
comma-separated string. The old style will continue to work, but print a
warning, until the 16.09 release. An example of the new style:
fileSystems."/example" = {
device = "/dev/sdc";
fsType = "btrfs";
options = [ "noatime" "compress=lzo" "space_cache" "autodefrag" ];
};
CUPS, installed by services.printing module, now has its
data directory in /var/lib/cups. Old configurations
from /etc/cups are moved there automatically, but
there might be problems. Also configuration options
services.printing.cupsdConf and
services.printing.cupsdFilesConf were removed because
they had been allowing one to override configuration variables required for
CUPS to work at all on NixOS. For most use cases,
services.printing.extraConf and new option
services.printing.extraFilesConf should be enough; if
you encounter a situation when they are not, please file a bug.
There are also Gutenprint improvements; in particular, a new option
services.printing.gutenprint is added to enable
automatic updating of Gutenprint PPMs; it's greatly recommended to enable
it instead of adding gutenprint to the
drivers list.
services.xserver.vaapiDrivers has been removed. Use
hardware.opengl.extraPackages{,32} instead. You can also
specify VDPAU drivers there.
programs.ibus moved to
i18n.inputMethod.ibus. The option
programs.ibus.plugins changed to
i18n.inputMethod.ibus.engines and the option to enable
ibus changed from programs.ibus.enable to
i18n.inputMethod.enabled.
i18n.inputMethod.enabled should be set to the used input
method name, "ibus" for ibus. An example of the new
style:
i18n.inputMethod.enabled = "ibus";
i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ anthy mozc ];
That is equivalent to the old version:
programs.ibus.enable = true;
programs.ibus.plugins = with pkgs; [ ibus-anthy mozc ];
services.udev.extraRules option now writes rules to
99-local.rules instead of
10-local.rules. This makes all the user rules apply
after others, so their results wouldn't be overriden by anything else.
Large parts of the services.gitlab module has been been
rewritten. There are new configuration options available. The
stateDir option was renamned to
statePath and the satellitesDir
option was removed. Please review the currently available options.
The option no longer
interpret the dollar sign ($) as a shell variable, as such it should not be
escaped anymore. Thus the following zone data:
\$ORIGIN example.com.
\$TTL 1800
@ IN SOA ns1.vpn.nbp.name. admin.example.com. (
Should modified to look like the actual file expected by nsd:
$ORIGIN example.com.
$TTL 1800
@ IN SOA ns1.vpn.nbp.name. admin.example.com. (
service.syncthing.dataDir options now has to point to
exact folder where syncthing is writing to. Example configuration should
look something like:
services.syncthing = {
enable = true;
dataDir = "/home/somebody/.syncthing";
user = "somebody";
};
networking.firewall.allowPing is now enabled by default.
Users are encouraged to configure an appropriate rate limit for their
machines using the Kernel interface at
/proc/sys/net/ipv4/icmp_ratelimit and
/proc/sys/net/ipv6/icmp/ratelimit or using the
firewall itself, i.e. by setting the NixOS option
networking.firewall.pingLimit.
Systems with some broadcom cards used to result into a generated config
that is no longer accepted. If you get errors like
error: path ‘/nix/store/*-broadcom-sta-*’ does not exist and cannot be created
you should either re-run nixos-generate-config or
manually replace
"${config.boot.kernelPackages.broadcom_sta}" by
config.boot.kernelPackages.broadcom_sta in your
/etc/nixos/hardware-configuration.nix. More discussion
is on the
github issue.
The services.xserver.startGnuPGAgent option has been
removed. GnuPG 2.1.x changed the way the gpg-agent works, and that new
approach no longer requires (or even supports) the "start everything as a
child of the agent" scheme we've implemented in NixOS for older versions.
To configure the gpg-agent for your X session, add the following code to
~/.bashrc or some file that’s sourced when your
shell is started:
GPG_TTY=$(tty)
export GPG_TTY
If you want to use gpg-agent for SSH, too, add the following to your
session initialization (e.g.
displayManager.sessionCommands)
gpg-connect-agent /bye
unset SSH_AGENT_PID
export SSH_AUTH_SOCK="''${HOME}/.gnupg/S.gpg-agent.ssh"
and make sure that
enable-ssh-support
is included in your ~/.gnupg/gpg-agent.conf. You will
need to use ssh-add to re-add your ssh keys. If gpg’s
automatic transformation of the private keys to the new format fails, you
will need to re-import your private keyring as well:
gpg --import ~/.gnupg/secring.gpg
The gpg-agent(1) man page has more details about this
subject, i.e. in the "EXAMPLES" section.
Other notable improvements:
ejabberd module is brought back and now works on NixOS.
Input method support was improved. New NixOS modules (fcitx, nabi and
uim), fcitx engines (chewing, hangul, m17n, mozc and table-other) and ibus
engines (hangul and m17n) have been added.
