An escape char is needed to prevent "$ nix" from being evaluated and
expanded to an empty string. With this change the resulting text is
$ nix-env -qaP | grep wget
instead of
-env -qaP | grep wget
systemd escaping rules translate this into a string containing '\'
which is treated by some code paths as quoted, and by others as unquoted
causing the affected units to fail.
Currently, the restartTriggers are abusing the systemd unit file in that
the cfg.carbon.config/storageAggregation/... option text is pasted into
the unit file. Even though this sort-of works (the service is restarted
if the config changes) this causes systemd to print error messages about
invalid sections (rightfully so!).
The correct use of restartTriggers is to list storage paths, which is
what this change does. If any of the
cfg.carbon/config/storageAggregation/... options change, configDir will
get a new hash. It is not as "fine grained" as the current version, but
it is not abusing the interface.
Also, remove unneeded 'waitress' in one of the restartTriggers, because
it is already listed as part of the service config.
When formatting a nixos usb using my windows machine I noticed that the
disk labeling using periods was not compatible with my linux kernel /
udev recognition. When labeling a volume NIXOS_14.10 under Windows, it would
show up as NIXOS_14_10 on NixOS. This meant that /dev/root would never come
up at boot time, preventing the livecd from starting.
This patch works around this issue by eliminating any special characters
other than underscores. The previous versioning didn't seem all that
useful, especially when consdering there are many different version of
the year.month named iso.
graphitePort must point to the port that carbon-cache listens on, not

With this change I finally got data from statsd to graphite.
It's "aggregation" with two 'g's.

One reason for adding this is to make Chromium able to open files it has

Currently this happens:

Looking into xdg-open, one can see that it first tries to run gvfs-open

be used on HVM instances without needing nixops. Previously
the grub setup was incorrect, so a plain 'nixos-rebuild switch'
and a reboot would result in a broken system.
Also added growing of the partition of the root disk in the initrd,
so you can run resize2fs after initial boot, without needing an
extra reboot. This is useful especially for nixops'
deployment.ec2.ebsInitialRootDiskSize option.

Restarting user@ instances is bad because it causes all user services
(such as ssh-agent.service) to be restarted. Maybe one day we can have
switch-to-configuration restart user units in a fine-grained way, but
for now we should just ignore user systemd instances.

This now provides a handful of different grsecurity kernels for slightly
different 'flavors' of packages. This doesn't change the grsecurity
module to use them just yet, however.

AppArmor only requires a few patches to the 3.2 and 3.4 kernels in order
to work properly (with the minor catch grsecurity -stable includes the
3.2 patches.) This adds them to the kernel builds by default, removes
features.apparmor (since it's always true) and makes it the default MAC
system.

"nixos-install --chroot" runs a command (by default a login shell) in
a chroot inside the NixOS installation in /mnt. This might useful for
poking around a new installation.
By setting a line like
MACVLANS="eno1"
in /etc/containers/<name>.conf, the container will get an Ethernet
interface named mv-eno1, which represents an additional MAC address on
the physical eno1 interface. Thus the container has direct access to
the physical network. You can specify multiple interfaces in MACVLANS.
Unfortunately, you can't do this with wireless interfaces.
Note that dhcpcd is disabled in containers by default, so you'll
probably want to set
networking.useDHCP = true;
in the container, or configure a static IP address.
To do: add a containers.* option for this, and a flag for
"nixos-container create".
This allows you to use the Linux kernel's built-in compressed memory as

It is recommended to enable only for kernel 3.14 (which is when zram came out of

This overhauls the Datadog module a bit to be much more useful. In
particular, it adds support for nginx and postgresql monitoring
integrations to dd-agent. These have to exist in separate files under
/etc/dd-agent, so the module just exposes then as separate options. In
the future, more integrations could be added this way.
In the process of doing this, I also had to rename the dd-agent user to
datadog. Note the UIDs did not change, so this is strictly backwards
compatible. The reason for this is to make it easier to create a
'datadog' postgres user with access to pg_stats, as 'dd-agent' typically
isn't a valid username. This allows the out of the box configurations to
be used.

If /boot is a btrfs subvolume, it will be on a different device than /
but not be at the root from grub's perspective. This should be fixed in
a nicer way by #2449, but that can't go into 14.04.
Hopefully fixes failures like:

This shouldn't be necessary, but it might be that the use of unionfs
is interfering with a clean shutdown.
Dmidecode fails in our EFI test with the error "SMBIOS entry point
missing". But we don't need dmidecode because we have already have
systemd-detect-virt.
NixOS has a pervasive dependency on bash. For instance, the X11
session script sources /etc/profile to get a reasonable
environment. Thus we should not provide an option to disable bash.
Also, enabling zsh no longer sets ‘users.defaultUserShell’ to zsh, to
prevent a collision with bash's definition of the same
option. (Changing the default shell is also something that should be
left to the user.)
Previously all card-specific stuff was scattered across xserver.nix
and opengl.nix, which is ugly. Now it can be kept together in a single
card-specific module. This required the addition of a few internal
options:
- services.xserver.drivers: A list of { name, driverName, modules,
libPath } sets.
- hardware.opengl.package: The OpenGL implementation. Note that there
can be only one OpenGL implementation at a time in a system
configuration (i.e. no dynamic detection).
- hardware.opengl.package32: The 32-bit OpenGL implementation.
Fixes#2379.
The new name was a misnomer because the values really are X11 video
drivers (e.g. ‘cirrus’ or ‘nvidia’), not OpenGL implementations. That
it's also used to set an OpenGL implementation for kmscon is just
confusing overloading.
release.nix and release-combined.nix current hardcode the systems which
they are built for. This change introduces an argument to the
expressions called supportedSystems, which allows the builder to choose
which architectures he wants to build. By default, this uses the same
linux x86_64 and i686 architectures.
The Tarsnap module is now far more flexible, allowing individual
archives with individual options to be specified at will, allowing
granular backup schedules, etc.

This reverts commit 6eaced3582. Doesn't
work very well, e.g. if you actually have the FUSE module loaded. And
in any case it's already fixed in NixOps.
Otherwise, when switching from systemd 203 to 212, you get errors like:
Failed to stop remote-fs.target: Bad message
Failed to stop systemd-udevd-control.socket: Bad message
...
These fail to mount if you don't have the appropriate kernel support,
and this confuses NixOps' ‘check’ command. We should teach NixOps not
to complain about non-essential mount points, but in the meantime it's
better to turn them off.
By default, socat only waits 0.5s for the remote side to finish after
getting EOF on the local side. So don't close the local side, instead
wait for socat to exit when the remote side finishes.

This fixes several problems in the dhcpcd service:
* A segfault during startup, due to a race with udev (dhcpcd would get
an ADD event from udev, causing it to re-add an interface that it
already had, leading to a segfault later on).
* A hang/segfault processing "dhcpcd rebind" (which NixOS calls after
waking up from suspend).
Also, add "lo" to the list of ignored interfaces. It usually ignores
"lo", but apparently not when it gets an ADD event from udev.
Upstream has not been tagging new versions for a long time, but we need
compatibility with newer kernels. The 0.6.2 versions already have a bunch of
backported compatibility patches, but 3.14 kernels need even more.
Also, the git versions have fixed a bunch of crashes and other bugs, so perhaps
we should just bite the bullet and just use recent git versions (as sometimes
upstream recommends, when people run into bugs).
This adds a new "boot.zfs.useGit" boolean option, so that a user can
easily opt into using the git versions.
By enabling ‘services.openssh.startWhenNeeded’, sshd is started
on-demand by systemd using socket activation. This is particularly
useful if you have a zillion containers and don't want to have sshd
running permanently. Note that socket activation is not noticeable
slower, contrary to what the manpage for ‘sshd -i’ says, so we might
want to make this the default one day.
Only one process can interact with the TPM module and
that process should be tcsd. The tpm_rng kernel module
should instead be loaded and /dev/hwrnd be used to
read the TPM random generator.
Also, log which random generator devices are used by
rngd on startup.
This causes OpenVPN services to reach the "active" state when the VPN
connection is up (i.e., after OpenVPN prints "Initialization Sequence
Completed"). This allows units to be ordered correctly after openvpn-*
units, and makes systemctl present a password prompt:
$ start openvpn-foo
Enter Private Key Password: *************
(I first tried to implement this by calling "systemd-notify --ready"
from the "up" script, but systemd-notify is not reliable.)
This seems to have combined badly with the systemd upgrade, we'll revert
for now and revisit after the 14.04 branch.
This reverts commit ad80532881, reversing
changes made to 1c5d3c7883.
The ability for unprivileged users to mount external media is useful
regardless of the desktop environment. Also, since udisks2 is
activated on-demand, it doesn't add any overhead if you're not using it.
Apparently systemd is now smart enough to figure out predictable names
for QEMU network interfaces. But since our tests expect them to be
named eth0/eth1..., this is not desirable at the moment.

This used to work with systemd-nspawn 203, because it bind-mounted
/etc/resolv.conf (so openresolv couldn't overwrite it). Now it's just
copied, so we need some special handling.
This led to the container test failing, which made no sense
whatsoever, until I realized nix-daemon.socket creates the socket
directory as a side effect, which systemd-nspawn then bind-mounts.

This has some advantages:
* You get ssh-agent regardless of how you logged in. Previously it was
only started for X11 sessions.
* All sessions of a user share the same agent. So if you added a key
on tty1, it will also be available on tty2.
* Systemd will restart ssh-agent if it dies.
* $SSH_AUTH_SOCK now points to the /run/user/<uid> directory, which is
more secure than /tmp.
For bonus points, we should patch ssh-agent to support socket-based
activation...
With ‘systemd.user.units’ and ‘systemd.user.services’, you can specify
units used by per-user systemd instances. For example,
systemd.user.services.foo =
{ description = "foo";
wantedBy = [ "default.target" ];
serviceConfig.ExecStart = "${pkgs.foo}/bin/foo";
};
declares a unit ‘foo.service’ that gets started automatically when the
user systemd instance starts, and is stopped when the user systemd
instance stops.
Note that there is at most one systemd instance per user: it's created
when a user logs in and there is no systemd instance for that user
yet, and it's removed when the user fully logs out (i.e. has no
sessions anymore). So if you're simultaneously logged in via X11 and a
virtual console, you get only one copy of foo.
If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.
This makes the baseUnit option unnecessary, so I've removed it.
This allows specifying rules for systemd-tmpfiles.
Also, enable systemd-tmpfiles-clean.timer so that stuff is cleaned up
automatically 15 minutes after boot and every day, *if* you have the
appropriate cleanup rules (which we don't have by default).
mkdir -m will only set the permissions if it *creates* the directory.
Existing directories, with possibly wrong permissions, will not be
updated.
Use explicit chmod so permissions will always be correct.
The preStart snippets (graphite, carbon) try to create directories under
/var/db/. That currently fails because the code is run as user
"graphite". Fix by setting "PermissionsStartOnly = true" so that the
preStart stuff is run as 'root'.
Further:
* graphite-web-0.9.12/bin/build-index.sh needs perl, so add it to PATH.
* Now that preStart runs as root, we must wait with "chown graphite"
until we're done creating files/directories.
* Drop needless check for root (uid 0) before running chown.
This creates static device nodes such as /dev/fuse or
/dev/snd/seq. The kernel modules for these devices will be loaded on
demand when the device node is opened.
