From Postfix documentation:
With this setting, the Postfix SMTP server will not reject mail with "User
unknown in local recipient table". Don't do this on systems that receive mail
directly from the Internet. With today's worms and viruses, Postfix will become
a backscatter source: it accepts mail for non-existent recipients and then
tries to return that mail as "undeliverable" to the often forged sender
address.
The tag wasn't properly closed which caused the manual build to fail.

This patch add a new argument to Nixpkgs default expression named "overlays".
By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`,
or from the directory `~/.nixpkgs/overlays/`. If the environment variable does not name a valid directory
then this mechanism would fallback on the home directory. If the home directory does not exists it will
fallback on an empty list of overlays.
The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the
content of Nixpkgs, with additional set of packages. The overlays, i-e directory, files, symbolic links
are used in alphabetical order.
The simplest overlay which extends Nixpkgs with nothing looks like:
```nix
self: super: {
}
```
More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query
the final result of the fix-point.
An example of overlay which extends Nixpkgs with a small set of packages can be found at:
https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix
To use this file, checkout the repository and add a symbolic link to
the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.
Network Manager calls dhclient on container interfaces and fails
which locks you out of the container after a few seconds, unless
you tell it not to manage these interfaces.

41c8aa8d6 ("php: change config-file-scan-dir from /etc to /etc/php.d")
were merged to master _after_ NixOS 16.09. Commit 351d12437 then wrongly
updated the NixSO 16.09 release notes. Fix by moving the entry to NixOS
17.03.
`stripHash` documentation states that it prints out the stripped name to
the stdout, but the function stored the value in `strippedName`
instead.
Basically all usages did something like
`$(stripHash $foo | echo $strippedName)` which is just braindamaged.
Fixed the implementation and all invocations.
This introduces VirtualBox version 5.1.6 along with a few refactored
stuff, notably:
* Kernel modules and user space applications are now separate
derivations.
* If config.pulseaudio doesn't exist in nixpkgs config, the default is
now to build with PulseAudio modules.
* A new updater to keep VirtualBox up to date.
All subtests in nixos/tests/virtualbox.nix succeed on my machine and
VirtualBox was reported to be working by @DamienCassou (although with
unrelated audio problems for another fix/branch) and @calbrecht.
The change is backwards-compatible for users of the NixOS module but not
if people were using the package directly, so let's warn users about
that.

Before this commit updating /var/setuid-wrappers/ folder introduced
a small window where NixOS activation scripts could be terminated
and resulted into empty /var/setuid-wrappers/ folder.
That's very unfortunate because one might lose sudo binary.
Instead we use two atomic operations mv and ln (as described in
https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/)
to achieve atomicity.
Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints
were removed in installation scripts and in boot process.
Tested:
- upgrade /var/setuid-wrappers/ from folder to a symlink
- make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted
This removes our hardcoded presets which weren't updated for quite some time.
Infinality now has new hardcoded presets in freetype, which can be overriden if
desired with environment variables (as before). Accordingly, updated NixOS
module to set the hardcoded preset.
Additionally used a more "right" type for substitutions.
The name gitlab-runner clashes with a component of Gitlab CI with the
same name and only confuses people. It's now called gitlab-bundle and
a convenience-script gitlab-rake for easier invocation of rake tasks
was added. This was the primary use case of gitlab-runner.
In light of Emacs packaging improvements such as those mentioned
in #11503, and with the addition of a systemd service (#15807
and #16356), and considering that the wiki page is completely
out of date (#13217), it seems that some documentation is in order.
Enabling EFI runtime services provides a venue for injecting code into
the kernel.
When grsecurity is enabled, we close this by default by disabling access
to EFI runtime services. The upshot of this is that
/sys/firmware/efi/efivars will be unavailable by default (and attempts
to mount it will fail).
This is not strictly a grsecurity related option, it could be made into
a general option, but it seems to be of particular interest to
grsecurity users (for non-grsecurity users, there are other, more
immediate kernel injection attack dangers to contend with anyway).
* Hydra doesn't like spaces in filenames.
* The zip file contained nix/store/.../OEBPS rather than OEBPS at
top-level, causing some programs (like okular) to barf.
* Remove the redundant $dst/epub directory.
* manual: Mark commands that require root
Mark every command that requires to be run as root by prefixing them
with '#' instead of '$'.
* manual: Add note about commands that require root
When displaying a warning about a removed Option we should always
include reasoning why it was removed and how to get the same
functionality without it.

with an empty string).
startGnuPGAgent: further notes on replacement
This allows setting options for the same LUKS device in different
modules. For example, the auto-generated hardware-configuration.nix
can contain
boot.initrd.luks.devices.crypted.device = "/dev/disk/...";
while configuration.nix can add
boot.initrd.luks.devices.crypted.allowDiscards = true;
Also updated the examples/docs to use /disk/disk/by-uuid instead of
/dev/sda, since we shouldn't promote the use of the latter.
This allows to use <olink> tags inside NixOS options to reference
sections from the manual. I've originally introduced it in #14476 to
reference the Taskserver specific documentation from the options
reference but as suggested by @nbp, this was done as a separate pull
request to ensure greater visibility rather than being "hidden" in the
Taskserver branch.
The build time for the manual is around 30s on my machine without this
change and 34s with this change, so it shouldn't have a very big impact
on the build time of the manual.
Olinks between the options reference and the manual now will look like
this:
"More instructions about NixOS in conjuction with Taskserver can be
found in the NixOS manual at Chapter 15, Taskserver."
More documentation about olinks can be found here:

This command was useful when NixOS was spread across multiple
repositories, but now it's pretty pointless (and obfuscates what
happens, i.e. "git clone git://github.com/NixOS/nixpkgs.git").
This adds a Taskserver module along with documentation and a small
helper tool which eases managing a custom CA along with Taskserver
organisations, users and groups.
Taskserver is the server component of Taskwarrior, a TODO list
application for the command line.
The work has been started by @matthiasbeyer back in mid 2015 and I have
continued to work on it recently, so this merge contains commits from
both of us.
Thanks particularly to @nbp and @matthiasbeyer for reviewing and
suggesting improvements.
I've tested this with the new test (nixos/tests/taskserver.nix) this
branch adds and it fails because of the changes introduced by the
closure-size branch, so we need to do additional work on base of this.
This reverts commit 1d77dcaed3.
It will be reintroduced along with #14700 as a separate branch, as
suggested by @nbp.
I added this to this branch because I thought it was a necessary
dependency, but it turns out that the build of the manual/manpages still
succeeds and merely prints a warning like this:
warning: failed to load external entity "olinkdb.xml"
Olink error: could not open target database 'olinkdb.xml'.
Error: unresolved olink: targetdoc/targetptr = 'manual/module-taskserver'.
The olink itself will be replaced by "???", so users looking at the
description of the option in question will still see the reference to
the NixOS manual, like this:
More instructions about NixOS in conjuction with Taskserver can be found
in the NixOS manual at ???.

My first attempt to do this was to just use a conditional <refsection/>
in order to not create exact references in the manpage but create the
reference in the HTML manual, as suggested by @edolstra on IRC.
Later I went on to use <olink/> to reference sections of the manual, but
in order to do that, we need to overhaul how we generate the manual and
manpages.
So, that's where we are now:
There is a new derivation called "manual-olinkdb", which is the olinkdb
for the HTML manual, which in turn creates the olinkdb.xml file and the
manual.db. The former contains the targetdoc references and the latter
the specific targetptr elements.
The reason why I included the olinkdb.xml verbatim is that first of all
the DTD is dependent on the Docbook XSL sources and the references
within the olinkdb.xml entities are relative to the current directory.
So using a store path for that would end up searching for the manual.db
directly in /nix/store/manual.db.
Unfortunately, the <olinks/> that end up in the output file are
relative, so for example if you're clicking on one of these within the
PDF, the URL is searched in the current directory.
However, the sections from the olink's text are still valid, so we could
use an alternative URL for that in the future.
The manual doesn't contain any links, so even referencing the relative
URL shouldn't do any harm.

Unetbootin works by altering the image and placing a boot loader on it.
For this reason, it cannot work with UEFI and the installation guides
for other distributions (incl. Debian and Fedora) recommend against
using it.
Since dd writes the image verbatim to the drive, and not just the files,
it is not necessary to change the label after using it for UEFI
installations.

First of all this fixes an evaluation error I introduced in ae466ba,
which wasn't triggered by any of my own tests against the change because
there are usually no NixOS options that are declared outside of the
<nixpkgs> tree. I renamed the attribute name from "fn" to "fileName"
first and later to "fullPath" but forgot one still occuring "filename".
Thanks to @vcunat for noticing this.
Another thing that he pointed out was that the "stripPrefix" function
can be factored away entirely, because it's very similar to
"removePrefix" in <nixpkgs/lib>.
Unfortunately we can't use "removePrefix" as is, because we need to
account for the final shlash.
So instead of removing it twice and/or retaining "stripPrefix", let's
append a shlash on every "prefixesToStrip" and we can use "removePrefix"
as is.

Let's use a simple (unflipped) fold and break out the actual core
stripPrefix function from stripAnyPrefixes (I personally love
point-less^H^H^H^Hfree style but if I'd be anal I'd even go further and
factor away the "fn:").
Also, let's use path as a better name for "fn" (filename), because
that's what it is and also cannot be confused with "fn" meaning
"function".
We now toString all of the prefixes, so there shouldn't be any need to
implicily toString the extraSources anymore.

Regression introduced by e6cd147ae7.
This broke all of the installer tests, because they needed to rebuild
the manual within the test machine, while it only has a closure of the
already pre-built system in place.
The problem here was just that the order of the arguments got mixed up
in stripAnyPrefixes, so it was actually trying to strip the path off the
prefix, not the other way around.
So in the end no prefix was stripped at all, so we ended up having full
store paths in the manual, which in turn caused the build within the VM
to fail, because the prefixes differed.

For example, this allows writing

Also, document types.package in the manual.
The rationale for disabling this is: 1) systemd timers are better; 2)
it gets rid of one usually unnecessary process, which makes containers
more light-weight.
Note that cron is still enabled if services.cron.systemCronJobs is
non-empty, so this only matters if you have no declarative cron jobs
but do have user cron jobs.
Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.
Other distros have similar defaults, at least on Arch:
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
CONFIG_FB_VESA=m
CONFIG_FRAMEBUFFER_CONSOLE=y
Fixes#8139
By default this is now enabled, and it has to be explicitely enabled
using "enableOCR = true". If it is set to false, any usage of
getScreenText or waitForText will fail with an error suggesting to pass
enableOCR.
This should get rid of the rather large dependency on tesseract which
we don't need for most tests.
Note, that I'm using system("type -P") here to check whether tesseract
is in PATH. I know it's a bashism but we already have other bashisms
within the test scripts and we also run it with bash, so IMHO it's not a
problem here.

As promised in the previous commit, this can be used similarly to

Basically, this creates a screenshot and throws tesseract at it to
recognize the characters from the screenshot. In order to produce a
result that is well enough, we're using lanczos scaling and scale the
image up to 400% of its original size.
This provides the base functionality for a new Machine method which will
be called waitForText. I originally had that idea long ago when writing
the VM tests for VirtualBox and Chromium, but thought it would be
disproportionate to the case.
The downside however is that VM tests now depend on tesseract, but given
the average runtime of our tests it really shouldn't have a too big
impact and it's only a runtime dependency after all.
Another issue is that the OCR process takes quite some time to finish,
but IMHO it's better (as in more deterministic) than to rely on sleep().
