Take two of #40708 (4fe2898608).
That PR attempted to bidirectionally default `config.nixpkgs.system` and
`config.nixpkgs.localSystem.system` to each be updated by the other. But
this is not possible with the way the module system works. Divergence in
certain cases in inevitable.
This PR is more conservative and just has `system` default `localSystem`
and `localSystem` make the final call as-is. This solves a number of
issues.
- `localSystem` completely overrides `system`, just like with nixpkgs
proper. There is no need to specify `localSystem.system` to clobber the
old system.
- `config.nixpkgs.localSystem` is exactly what is passed to nixpkgs. No
spooky steps.
- `config.nixpkgs.localSystem` is elaborated just as nixpkgs would so
that all attributes are available, not just the ones the user
specified.
The remaining issue is just that `config.nixpkgs.system` doesn't update
based on `config.nixpkgs.localSystem.system`. It should never be
referred to lest it is a bogus stale value because
`config.nixpkgs.localSystem` overwrites it.
Fixes#46320
This adds several improvements the previously introduced
`services.weechat` module:
* Dropped `services.weechat.init` as the initialization script can now
be done on package-level since 2af41719bc using the `configure`
function.
* Added `sessionName` option to explicitly configure a name for the
`screen` session (by default: weechat-screen).
* Added `binary` option to configure the binary name (e.g.
`weechat-headless`).
* Added docs regarding `screen` session and `weechat.service`.
Previously it was only possible to use very simple Riemann config.
For more complicated scenarios you need a directory of clojure
files and the config file that riemann starts with should be in this
directory.
This fixes an issue with shells like fish that are not fully POSIX
compliant. The syntax `ENV=val cmd' doesn't work properly in there.
This issue has been addressed in #45932 and #45945, however it has been
recommended to use a single shell (`stdenv.shell' which is either
`bash' or `sh') to significantly reduce the maintenance overload in the
future.

Some programs like eog seem to need dconf accessible on dbus.
Without this change I get
(eog:1738): dconf-WARNING **: 21:20:52.770: failed to commit changes to
dconf: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
ca.desrt.dconf was not provided by any .service files
Although double '/' in paths is not a problem for GRUB supplied with nixpkgs, sometimes NixOS's grub.conf read by external GRUB and there are versions of GRUB which fail
The switch from slim to lightdm in #30890 broke some nixos tests
because lightdm by default doesn't permit auto-login for root.
Override /etc/pam.d/lightdm-autologin to allow it.
The option was added in 1251b34b5b
with type `types.path` but default `null`, so eval failed with
the default setting. This broke the acme and certmgr tests.

This is the semantics as understood by `xdg-open`. Using these semantics
on a non-colon-separated variable works because it acts as if it was a
one element long list.
This fixes an issue where it would try to exec
`google-chrome-beta:google-chrome:chromium:firefox` on a system
configured with these semantics in mind.
The instructions to install nixos behind a proxy were not clear. While
one could guess that setting http_proxy variables can get the install
rolling, one could end up with an installed system where the proxy
settings for the nix-daemon are not configured.
This commit updates the documentation with
1. steps to install behind a proxy
2. configure the global proxy settings so that nix-daemon can access
internet.
3. Pointers to use nesting.clone in case one has to use different proxy
settings on different networks.
Switch from slim to lightdm as the display-manager.
If plasma5 is used as desktop-manager use sdddm.
If gnome3 is used as desktop-manager use gdm.

The recommended TLS configuration comes with `ssl_stapling on` and
`ssl_stapling_verify on`. However, this last directive also requires
the use of `ssl_trusted_certificate` to verify the received answer.
When using `enableACME` or similar, we can help the user by providing
the correct value for the directive.
The result can be tested with:
openssl s_client -connect web.example.com:443 -status 2> /dev/null
Without OCSP stapling, we get:

A shared exported guard `__NIXOS_SET_ENVIRONMENT_DONE` is introduced that can
be used to prevent child shells from sourcing `system.build.setEnvironment`
the second time.
This fixes e.g. `nix run derivation` when run from e.g. ZSH through the console or
ssh. Before this Bash would resource the common environment resetting the `PATH`
environment variable.
We also export `system.build.setEnvironment` to `/etc/set-environment` making it
easy to reset the common environment with `. /etc/set-environment` when
needed and to grep for environment variables in `/etc` (which was the
motivation of #30418).
This reverts changes made in b00a3fc6fd
(the original #30418).
This allows one to add rules which change a packet's routing table:
iptables -t raw -I PREROUTING 1 -m set --match-set myset src -j MARK --set-mark 2
ip rule add fwmark 2 table 1 priority 1000
ip route add default dev wg0 table 1
to the beginning of raw table PREROUTING chain, and still have rpfilter.
DefaultTimeoutStartSec is normally set to 90 seconds and works fine. But
when running NixOS tests on a very slow machine (like a VM without
nested virtualisation support) this default is to low and causes
systemd units to fail spuriously. One symptom of this issue are tests
at times failing with "timed out waiting for the VM to connect".
Since the VM connect timeout is 300 seconds I also set
DefaultTimeoutStartSec to this which is ridiculously high.
The background color option is self-explanatory.
The mode is either `normal` or `stretch`, they are as defined by GRUB,
where normal will put the image in the top-left corner of the menu, and
stretch is the default, where it stretches the image without
consideration for the aspect ratio.

The wallpaper used is *structurally compatible* with the other one,
meaning that the logo is at the same location, and not bigger.
It has one drawback: the logo is brighter, which clashes with the grub
usage. This is to be fixed with new options in grub.
- default coreutils is stripped of /share/ (11 -> 2 MiB)
- coreutils-full retains /share/ and adds openssl for faster *sum tools
- NixOS systemPackages contains coreutils-full
- *Support parameter defaults are moved inside
(it seemed confusing to have `? false` and "at once" with `? isLinux`)
Closure considerations:
+ typical build-time closure will get lighter by ~9 MiB
- typical closure of NixOS installation will grow by ~2 MiB,
due to referring to both versions. I think it would be possible to
re-use most of the utils between the two versions, but the expression
would get much more complex.
I considered having stdenv with minimal coreutils and the default
`coreutils` attribute being full, but it turned out there were too many
trivial references in nixpkgs, so it didn't seem easy to keep rebuild
impact of openssl from growing significantly.
The additions are:
- image/svg+xml for SVG images
- application/atom+xml for Atom feeds
These types are also present in mime.types. For better readability,
the list is sorted and formatted with one type per line.
