Without configuring the block size a default of 512 bytes is used, which can
slow down the transfer speed massively.
In a test I've done with a semi-decent USB stick, I only get a transfer speed
of around 180 KB/sec when not specifying the block size but see 27 MB/sec when
setting the block size to 1 MB. This makes the transfer of the minimal
installation ISO take half a minute instead of an hour.

Lo and behold, we're finally catching up with Mozillas very own firefox
build in terms of speed.
PGO is an optimization technique in which in a first step we create a
build that supports instrumentation, meaning we can use it to create a
profile of how the browser behaved during usage. Then in a second pass
we create the final build that uses the acquired profiling data to
optimize the browser for the workload it actually received during
profiling.
The downside is that with PGO we now need to build Firefox twice, which
increases the build time from around 20 minutes to roughly 50 minutes.
In the Speedometer 2.0 benchmark multiple tests could see a
responsiveness improvemeant around 20-25%, which makes the increased
build time well worth it.
Sadly this benefit seems limited to x86_64-linux, builds on
aarch64-linux get stuck during profiling and I haven't found out why.
Finally, after a long time, we can say:
Closes: #76484
Supersedes: #129503
The current wrapper only includes vim, gvim and the man pages
(optionally). This rewrite distinguishes two scenarios, which I expect
cover the majority of use cases:
- standalone mode, when `name != "vim"`, means the user already has a
vim in scope and only wants to add a customized version with a
different name. In this case we only include wrappers for `/bin/*vim`.
- non-standalone mode, when `name == "vim"`, means the user expects a
normal vim package that uses the specified configuration. In this case
we include everything in the original derivation, with wrappers for
all the executables that accept a vimrc.
When a NixOS system uses flakes, i.e., /etc/nixos/flake.nix exists, it
is impossible to use nixos-rebuild to build a pre-flake
configuration.nix. Of course, one can directly use nix command to
build the configuration, but not everybody remembers the correct nix
options to do that.
With the new option, it is possible to build a pre-flake configuration
with command like this:
nixos-rebuild build-vm -I nixos-config=./vm.nix --no-flake
The option might be useful for people following older pre-flake
tutorials on a flake-based system.
hostNames being deprecated makes configuring hosts with multiple keys a
pain. including the attr name of the entry in the host name list is a
nice convenience though, so we'll retain it and clarify the
documentation on how the actual host name list for an entry is put
together.
* _7zz: correct license and remove p7zip dependency
The code under Compress/Rar* is licensed under a specific unRAR license
Also Compress/LzfseDecoder.cpp is covered by BSD3
The unRAR code is removed from the `.tar.xz` since the license posits you
agree or remove the code from your hard drive
This adds some complexity to updating 7zz so there is also an update
script
Meta has been updated and tweaked
Source is now downloaded from sourceforge in the `.tar.xz` version to
avoid depending on p7zip
* _7zz: add notice of the license updates and optional unRAR licenced code
If `services.tor.client.enable` is set to false (the default), the `SOCKSPort` option is not added to the torrc file but since Tor defaults to listening on port 9050 when the option is not specified, the tor client is not actually disabled. To fix this, simply set `SOCKSPort` to 0, which disables the client.
Use `mkForce` to prevent potentially two different `SOCKSPort` options in the torrc file, with one of them being 0 as this would cause Tor to fail to start. When `services.tor.client.enable` is set to false, this should always be disabled.
pam-ussh allows authorizing using an SSH certificate stored in your

it's really easy to accidentally write the wrong systemd Exec* directive, ones

The current logic assumes that everything that isn't a derivation is a
store path, but it can also be something that's *coercible* to a store
path, like a flake input.
Unnecessary uses of `lib.toDerivation` result in errors in pure evaluation
mode when `builtins.storePath` is disabled.
Also document what a `package` is.

Explain why having legacy iptables rules installed can lead to confusing
firewall behaviour, and provide some guidance on how to fix this.
zsh-autosuggestions supports having fallback strategies expressed
through the ZSH_AUTOSUGGEST_STRATEGY array. For example,
`ZSH_AUTOSUGGEST_STRATEGY=(history completion)`. We should also support
this.
This adds an option `services.taskserver.openFirewall` to allow the user
to choose whether or not the firewall port should be opened for the
service. This is no longer the case by default.

This change probably wasn't documented sufficiently in the release
notes, neither the fact systemd stopped using iptables on its own in
case of nf_tables support.
Fixes#156041.
As explained in vpnc's Makefile, a vpnc with OpenSSL support is
non-redistributable. The option to enable OpenSSL support, which is
disabled by default, is even called OPENSSL_GPL_VIOLATION — something
that was conveniently hidden by the strange way the option was set in
the previous version of this package.
New ntopng version supports running as specified user. Create a separate
user for ntopng with a separate Redis instance.
Separate instance is only used for new `system.stateVersion`s to avoid
breaking existing setups. To configure that we add two new options,
`redis.address` and `redis.createInstance`. They can also be used to
specify your own Redis address.
The command in example is expected to be run from nixpkgs checkout, but
there's no explanation of this. Let's just use system nixpkgs: most
users will have it just working and those who use git checkouts will
figure it out.
After this change users with non-declarative configs need to set
`services.home-assistant.config` to an `null`, or their
`configuration.yaml` will be overwritten.
The reason for this is that with rfc42 style defaults the config
attribute set will never be empty by default.
--port and --address have both been deprecated and are nonfunctional
starting with kubernetes 1.23. Use --secure-port and --bind-address

Addresses #16545. Allows for user defined environment variables that
hold paths to wordlists. This is to allow for easy access to wordlists
for users and scripts, (in other distributions a convenient wordlist is
typically found in /usr/share/dict/words or similar). The default
wordlist is the one found in scowl, for no other reason than that's the
one that was mentioned in the linked issue.
It is possible to specify multiple environment variables as well. This
is for users who need multiple wordlists (such as multilingual users).
Adding a fake override function via passthru will at least give users of

The `nix.*` options, apart from options for setting up the
daemon itself, currently provide a lot of setting mappings
for the Nix daemon configuration. The scope of the mapping yields
convience, but the line where an option is considered essential
is blurry. For instance, the `extra-sandbox-paths` mapping is
provided without its primary consumer, and the corresponding
`sandbox-paths` option is also not mapped.
The current system increases the maintenance burden as maintainers have to
closely follow upstream changes. In this case, there are two state versions
of Nix which have to be maintained collectively, with different options
avaliable.
This commit aims to following the standard outlined in RFC 42[1] to
implement a structural setting pattern. The Nix configuration is encoded
at its core as key-value pairs which maps nicely to attribute sets, making
it feasible to express in the Nix language itself. Some existing options are
kept such as `buildMachines` and `registry` which present a simplified interface
to managing the respective settings. The interface is exposed as `nix.settings`.
Legacy configurations are mapped to their corresponding options under `nix.settings`
for backwards compatibility.
Various options settings in other nixos modules and relevant tests have been
updated to use structural setting for consistency.
The generation and validation of the configration file has been modified to
use `writeTextFile` instead of `runCommand` for clarity. Note that validation
is now mandatory as strict checking of options has been pushed down to the
derivation level due to freeformType consuming unmatched options. Furthermore,
validation can not occur when cross-compiling due to current limitations.
A new option `publicHostKey` was added to the `buildMachines`
submodule corresponding to the base64 encoded public host key settings
exposed in the builder syntax. The build machine generation was subsequently
rewritten to use `concatStringsSep` for better performance by grouping
concatenations.

SUID wrappers really shouldn't be enabled by default, unless a consumer
relies on them. So in my opinion this falls upon the desktop
environments if needed or a user to explicltly enable this if wanted.
Most desktop environments and services like CUPS already enable polkit
by default, that should really be sufficient.
Currently it's rather difficult to install tmux plugins. The process involves two steps:
1. Specify the correct `pkg.tmuxPlugins` package in `environment.systemPackages`
2. Adding to the configuration file to instantiate the plugin.

This option behaves exactly like `boot.extraModprobeConfig`, except that it also includes the generated modprobe.d file in the initrd.
Many years ago, someone tried to include the normal modprobe.d/nixos.conf file generated by `boot.extraModprobeConfig` in the initrd: 0aa2c1dc46. This file contains a reference to a directory with firmware files inside. Including firmware in the initrd made it too big, so the commit was reverted again in 4a4c051a95.
The `boot.extraModprobeConfig` option not changing the initrd caused me much confusion because I tried to set the maximum cache size for ZFS and it didn't work.

Now that the terraform 0.12 compatibility is not needed anymore, the
`terraform.withPlugins` and `terraform-providers.mkProvider`
implementations can be simplified.
Instead of building a bunch of bin wrappers on instantiation, the
providers are now stored in
`$out/libexec/terraform-providers/<registry>/<owner>/<name>/<version>/<os>_<arch>/terraform-provider-<name>_v<version>`
and then a simple `buildEnv` can be used to merge them.
This breaks back-compat so it's not possible to mix-and-match with
previous versions of nixpkgs. In exchange, it now becomes possible to
use the providers from
[nixpkgs-terraform-providers-bin](https://github.com/numtide/nixpkgs-terraform-providers-bin)
directly.

Build DB from MD

(Amended) Build DB from MD (again)
This replaces the naive K=V unit parser with a proper INI parser from a
library and adds proper support for override files. Also adds a bunch of
comments about parsing, I hope this makes it easier to understand and
maintain in the future.
There are multiple reasons to do so, the first one is just general
correctness with is nice imo. But to get to more serious reasons (I
didn't put in all that effort for nothing) is that this is the first
step torwards more clever restart/reload handling. By using a library
like Data::Compare a future PR could replace the current way of
fingerprinting units (which is to compare store paths) by comparing the
hashes. This is more precise because units won't get restarted because
the order of the options change, comments are added, some dependency of
writeText changes, .... Also this allows us to add a feature like
`X-Reload-Triggers` so the unit can either be reloaded when these change
or restarted when everything else changes, giving module authors the
ability to have their services reloaded without having to fear that
updates are not applied because the service doesn't get restarted.
Another reason why this feature is nice is that now that the unit files
are parsed correctly (and values are just extracted from one section),
potential future rewrites can just rely on some INI library without
having to implement their own weird parser that is compatible with this
script.
This also comes with a new subroutine to handle systemd booleans because
I thought the current way of handling it was just ugly. This also allows
overriding values this script reads in an override file.
Apart from making this script more compatible with the world around it,
this also fixes two issues I saw bugging exactly 0 (zero) people. First
is that this script now supports multiple override files, also ones that
are not called override.conf and the second one is that `1` and `on` are
treated as bools by systemd but were previously not parsed as such by
switch-to-configuration.
Since release 1.18.4, the ModemManager daemon no longer automatically
performs the FCC unlock procedure by default. The user must, under their
own responsibility, enable the automatic FCC unlock as shipped by
ModemManager.
`assert` has the annoying property that it dumps a lot of code at the
user without the built in capability to display a nicer message. We have
worked around this using `assertMsg` which would *additionally* display
a nice message. We can do even better: By using `throw` we can make
evaluation fail before assert draws its conclusions and prevent it from
displaying the code making up the assert condition, so we get the nicer
message of `throw` and the syntactical convenience of `assert`.
Before:
nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
trace: Deterministic builds require stripping bytecode.
error: assertion (((lib).assertMsg (reproducibleBuild -> stripBytecode)) "Deterministic builds require stripping bytecode.") failed at /home/lukas/src/nix/nixpkgs/pkgs/development/interpreters/python/cpython/2.7/default.nix:45:1
After:
nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; }
error: Deterministic builds require stripping bytecode.
The `extraConfig` parameter only handles text - it doesn't support
arbitrary secrets and, with the way it's processed in the setup
script, it's very easy to accidentally unescape the echoed string and
run shell commands / feed garbage to bash.
To fix this, implement a new option, `config`, which instead takes a
typed attribute set, generates the `.env` file in nix and does
arbitrary secret replacement. This option is then used to provide the
configuration for all other options which change the `.env` file.
When upgrading bookstack, if something in the cache conflicts with the
new installation, the artisan commands might fail. To solve this, make
the cache lifetime bound to the setup service. This also removes the
`cacheDir` option, since the path is now handled automatically by
systemd.
This removes `/run/nixos/activation-reload-list` (which we will need in
the future when reworking the reload logic) and makes
`/run/nixos/activation-restart-list` honor `restartIfChanged` and
`reloadIfChanged`. This way activation scripts don't have to bother with
choosing between reloading and restarting.
Still actively developed and yet stuck on python2. Also marked as
vulnerable and their issue tracker contains yet another security issue
reported in 2021/10 that the upstream hasn't acknowledged yet.
Mind blown.

We take the idris2 projects version of the derivation. Originally,
Idris2 did not maintain their own nix derivation, so we created our
own. Now they maintain their own derivation, so we should try to
keep ours as close to theirs.
This change comes with the following differences:
* support files are in its own output, instead of packaged with idris2
- This makes it necessary to provide --package for contrib and network
!!! This is a breaking change !!!
* IDIRS2_PREFIX is set to ~/.idris2 instead of pointing to nix-store
- This makes --install work as expected for the user
* Properly set IDRIS2_PACKAGE_PATH
* non-linux platform uses chez-racket instead of chez
This renames our `firmwareLinuxNonfree` package to `linux-firmware`.
There is prior art for this in multiple other distros[1][2][3].
Besides making the package more discoverable by those searching for the
usual name, this also brings it in-line with the `kebab-case` we
normally see in `nixpkgs` pnames, and removes the `Nonfree` information
from the name, which I consider redundant given it's present in
`meta.license`.
The corresponding alias has been added, so this shouldn't break
anything.

Previously we allocated subuids automatically for all normal users.
Make this explicitly configurable, so that one can use this for system
users too (or explicitly disable for normal users). Also don't allocate
automatically by default if a user already has ranges specified statically.
