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.
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.

When rebuilding you have to manually run `systemctl --user
daemon-reload`. It gathers all authenticated users using
`loginctl list-user` and runs `daemon-reload` for each of them.
This is a first step towards a `nixos-rebuild` which is able to reload
user units from systemd. The entire task is fairly hard, however I
consider this patch usable as it allows to restart units without running
`daemon-reload` for each authenticated user.
This fixes an issue where setting both
`boot.loader.systemd-boot.editor` to `false` and
`boot.loader.systemd-boot.consoleMode` to any value would concatenate
the two configuration lines in the output, resulting in an invalid
`loader.conf`.
From reading the source I'm pretty sure it doesn't support multiple Yubikeys, hence
those options are useless.
Also, I'm pretty sure nobody actually uses this feature, because enabling it causes
extra utils' checks to fail (even before applying any patches of this branch).
As I don't have the hardware to test this, I'm too lazy to fix the utils, but
I did test that with extra utils checks commented out and Yubikey
enabled the resulting script still passes the syntax check.
Also reuse common cryptsetup invocation subexpressions.
- Passphrase reading is done via the shell now, not by cryptsetup.
This way the same passphrase can be reused between cryptsetup
invocations, which this module now tries to do by default (can be
disabled).
- Number of retries is now infinity, it makes no sense to make users
reboot when they fail to type in their passphrase.
This allows a developer to better identify in which snippet the
failure happened. Furthermore, users seeking help will have more
information available about the failure.
Problem: Restarting (stopping) system.slice would not only stop X11 but
also most system units/services. We obviously don't want this happening
to users when they switch from 18.03 to 18.09 or nixos-unstable.
Reason: The following change in systemd:
d8e5a93382
The commit adds system.slice to the perpetual units, which means
removing the unit file and adding it to the source code. This is done so
that system.slice can't be stopped anymore but in our case it ironically
would cause this script to stop system.slice because the unit file was
removed (and an older systemd version is still running).

Rather than special-casing the dns options in networkmanager.nix, use
the module system to let unbound and systemd-resolved contribute to
the newtorkmanager config.
find-libs is currently choking when it finds the dynamic linker
as a DT_NEEDED dependency (from glibc) and bails out like this
(as glibc doesn't have a RPATH):
Couldn't satisfy dependency ld-linux-x86-64.so.2
Actually the caller of find-libs ignores the exit status, so the issue
almost always goes unnoticed and happens to work by chance. But
additionally what happens is that indirect .so dependencies are
left out from the dependency closure calculation, which breaks
latest cryptsetup as libssl.so isn't found anymore.
This has been reported by @qknight in his Stack Overflow question:

The correct way to override a single value would be to use something
like this:
systemd.services.nagios.serviceConfig.Restart = lib.mkForce "no";
However, this doesn't work because the check is applied for the attrsOf
type and thus the attribute values might still contain the attribute set
created by mkOverride.
The unitOption type however did already account for this, but at this
stage it's already too late.
So now the actual value is unpacked while checking the values of the
attribute set, which should allow us to override values in
serviceConfig.

When a package contains a directory in one of the systemd directories
(like flatpak does), it is symlinked into the *-units derivation.
Then later, the derivation will try to create the directory, which
will fail:
mkdir: cannot create directory '/nix/store/…-user-units/dbus.service.d': File exists
builder for '/nix/store/…-user-units.drv' failed with exit code 1
Closes: #33233
GRUB 2.0 supports png, jpeg and tga. This will use the image's suffix to
load the right module.
As jpeg module is named jpeg, jpg is renamed jpeg.
If the user uses wrong image suffix for an image, it wouldn't work anyway.
This will leave up to two additional left-over files in /boot/ if user switches
through all the supported file formats. The module already left the png
image if the user disabled the splash image.
This is apparent from the service file directory in plymouth:
├── multi-user.target.wants
│ ├── plymouth-quit.service -> ../plymouth-quit.service
│ └── plymouth-quit-wait.service -> ../plymouth-quit-wait.service
Leaving it unspecified caused gdm-wayland to crash on boot, see #39615.
The change made other display managers not quit plymouth properly however. By
removing "multi-user.target" from `plymouth-quit.after` this is resolved.
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.
