Expose the path to a lesskey file as a module option. This makes it
possible to maintain a single lesskey file, used for both NixOS and
non-nix systems. An example of how this can be done follows.
1. Write a derivation that fetches lesskey from a known location:
{ stdenv, fetchgit }:
stdenv.mkDerivation {
name = "foo";
src = fetchgit { .. };
phases = [ "unpackPhase" "installPhase" ];
installPhase = "mkdir -p $out && cp $src/lesskey $out/lesskey";
}
2. Set programs.less.configFile to the corresponding path:
programs.less = {
enable = true;
configFile = "${pkgs.foo}/lesskey";
};
With #36556, a check was introduced to make sure the user and group
names do not exceed their respective maximum length. This is in part
because systemd also enforces that length, but only at runtime.
So in general it's a good idea to catch as much as we can during
evaluation time, however the maximum length of the group name was set to
16 characters according groupadd(8).
The maximum length of the group names however is a compile-time option
and even systemd allows more than 16 characters. In the mentioned pull
request (#36556) there was already a report that this has broken
evaluation for people out there.
I have also checked what other distributions are doing and they set the
length to either 31 characters or 32 characters, the latter being more
common.
Unfortunately there is a difference between the maximum length enforced
by the shadow package and systemd, both for user name lengths and group
name lengths. However, systemd enforces both length to have a maximum of
31 characters and I'm not sure if this is intended or just a off-by-one
error in systemd.
Nevertheless, I choose 32 characters simply to bring it in par with the
maximum user name length.
For the NixOS assertion however, I use a maximum length of 31 to make
sure that nobody accidentally creates services that contain group names
that systemd considers invalid because of a length of 32 characters.

This patch is heavily inspired by bd0d8ed807 which added
a setcap wrapper for `mtr` in order to allow running `mtr` without
`sudo`. The need for the capability `cap_net_raw` that can be registered using
`setcap` has been documented in the Arch Wiki: https://wiki.archlinux.org/index.php/Capabilities#iftop
A simple testcase has been added which starts two machines, one with a
setcap wrapper for `iftop`, one without. Both testcases monitor the
bandwidth usage of the machine using the options `-t -s 1` once, the
machine with setcap wrapper is expected to succeed, the `iftop` on the
machine without setcap wrapper is expected to return a non-zero exit
code.
- `localSystem` is added, it strictly supercedes system
- `crossSystem`'s description mentions `localSystem` (and vice versa).
- No more weird special casing I don't even understand
TEMP
service-runner had a backwards incompatible update, and parsoid 0.9.0
doesn't work with current stable MediaWiki. Instead use as a source
a repository with 0.8.0 and pinned service-runner version.
- Add `imageName` and `imageBaseName` options similar to the `isoName`
and `isoBaseName` options
- Make the filename of the iso match what iso-image.nix does
- Generate a nix-support/hydra-build-products like iso-image.nix does
* Fix reference CNI plugins
* The plugins were split out of the upstream cni repo around version
0.6.0
* Fix RBAC and DNS tests
* Fix broken apiVersion fields
* Change plugin linking to look in ${package}/bin rather than
${package.plugins}
* Initial work towards a working e2e test
* Test still fails, but at least the expression evaluates now

Without `ROOT_PATH` set, `gogs serv` tries to open logs in writing in
its store directory. This blocks cloning or pushing over ssh, and
results in a gogs internal error.
The original idea behind this change (described in ticket #11064) was to
improve the assertions to avoid that users of the X server accidentally
forget to configure a DM or WM.
However this caused several issues with setups that require X, but no DM
or WM. The keymap testcases became instable as well as now disabling DMs
needs to be done explicitly.
(see https://github.com/NixOS/nixpkgs/pull/31268#issuecomment-347080036)
In the end the idea behind the change and #11064 was obviously a
mistake, so reverting it completely for now should be fine.
The dovecot bump to 2.3.1 caused the dovecot service to fail to start
because it would try to chgrp sockets to dovecot whereas our default
dovecot group is called dovecot2.
This fixes the `update-locatedb` service when using the `mlocate`
package.
The service as-is does not properly handle flags during update of the
relevant database when configured to use the `mlocate` package.
The man entry for `updatedb` associated with `mlocate` does not say
that it supports environment variables in place of command line flags,
whereas the `findutils` package's updatedb does so.
To support this distinction, we pass the relevant settings as flags to
the `updatedb` program when using the `mlocate` package.
Fixes#29279
We should be able to deploy a NixOS 18.03 system with the current nixops
stable release. Some options were renamed, so instead of
`mkRenamedOptionModule` we introduce them as read-only interal options
that won't be rendered in the manual.
Only the options that are needed to make nixops evaluations succeed were
added.
This commit should probably be reverted after or before the 18.09 release,
depending on the nixops 1.6 release.
The user will not get the warning that these have been renamed but
this change is mentioned in the release notes.
Fixes#34253.
The isKexecable flag treated Linux without kexec as just a normal
variant, when it really should be treated as a special case incurring
complexity debt to support.
This service will never run automatically, but it encapsulates the
necessary logic and configuration to run a restore of the latest
archive, and allows to hook more specific logic, such as loading
a database dump, via `postStart`.
