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 withwmii_hg, butservices.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.services
wmiimenu 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.
{
imports = [ <nixpkgs/nixos/modules/services/misc/gitit.nix> ];
}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:
nginx.override {
modules = [ nginxModules.rtmp nginxModules.dav nginxModules.moreheaders ];
}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 attarsnap 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 services.xserver.enableCtrlAltBackspace
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 optionsservices.printing.cupsdConf andservices.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 optionservices.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 optionservices.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. Usehardware.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 toi18n.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. ThestateDir option was renamned tostatePath and the satellitesDir option
was removed. Please review the currently available options.
The option services.nsd.zones.<name>.data 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. $TTL 1800 @ IN SOA ns1.vpn.nbp.name. admin.example.com. (
service.syncthing.dataDir options now has to point
to exact folder where syncthing is writing to. Example configuration should
look something like:
services.syncthing = {
enable = true;
dataDir = "/home/somebody/.syncthing";
user = "somebody";
};networking.firewall.allowPing is now enabled by
default. Users are encourarged to configure an approiate rate limit for
their machines using the Kernel interface at/proc/sys/net/ipv4/icmp_ratelimit and/proc/sys/net/ipv6/icmp/ratelimit or using the
firewall itself, i.e. by setting the NixOS optionnetworking.firewall.pingLimit.
Systems with some broadcom cards used to result into a generated config that is no longer accepted. If you get errors like
error: path ‘/nix/store/*-broadcom-sta-*’ does not exist and cannot be created
you should either re-run nixos-generate-config or manually replace"${config.boot.kernelPackages.broadcom_sta}"
byconfig.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.
