nixos/installer: simplify and document wifi setup
The wpa_supplicant service in the NixOS installer is unusable because
the control socket is disabled and /etc/wpa_supplicant.conf ignored.

The manual currently recommends manually starting the daemon and using
wpa_passphrase, but this requires figuring out the interface name,
driver and only works for WPA2 personal networks.

By enabling the control socket, instead, a user can configure the
network via wpa_cli (or wpa_gui in the graphical installer), which
support more advanced network configurations.

As described in issue #81138, the Install section of upstream units is
currently ignored, so we make it part of the sysinit.target manually.

0b5fd3b784 qemu-guest: remove security.rngd setting
Since release 20.09 `rngd.enable` defaults to false, so this setting is redundant.

that `rngd` was enabled.

nixos/modules: add "sdhci_pci" to availableKernelModules
Encountered issues booting the live image on an Acer R11 Chromebook (CYAN). Got help from @samueldr on Freenode, and adding this module fixed it. Likely useful for other platforms/situations where booting from SD is necessary.

nixos/getty: rename from services.mingetty
It's been 8.5 years since NixOS used mingetty, but the option was
never renamed (despite the file definining the module being renamed in
9f5051b76c ("Rename mingetty module to agetty")).

I've chosen to rename it to services.getty here, rather than
services.agetty, because getty is implemantation-neutral and also the
name of the unit that is generated.

profiles/hardened: Add note about potential instability
Enabling the profile can lead to hard-to-debug issues, which should be

nixos/installer: enable sshd by default
Right now the UX for installing NixOS on a headless system is very bad.
To enable sshd without physical steps users have to have either physical
access or need to be very knowledge-able to figure out how to modify the
installation image by hand to put an `sshd.service` symlink in the
right directory in /nix/store. This is in particular a problem on ARM
SBCs (single board computer) but also other hardware where network is
the only meaningful way to access the hardware.

This commit enables sshd by default. This does not give anyone access to
the NixOS installer since by default. There is no user with a non-empty
password or key. It makes it easy however to add ssh keys to the
installation image (usb stick, sd-card on arm boards) by simply mounting
it and adding a keys to `/root/.ssh/authorized_keys`.
Importantly this should not require nix/nixos on the machine that
prepare the installation device and even feasiable on non-linux systems
by using ext4 third party drivers.

Potential new threats: Since this enables sshd by default a
potential bug in openssh could lead to remote code execution. Openssh
has a very good track-record over the last 20 years, which makes it
far more likely that Linux itself would have a remote code execution
vulnerability. It is trusted by millions of servers on many operating
systems to be exposed to the internet by default.

ad9bfe2254 nixos/hardened: enable user namespaces for root
linux-hardened sets kernel.unprivileged_userns_clone=0 by default; see
anthraxx/linux-hardened@104f44058f.

This allows the Nix sandbox to function while reducing the attack
surface posed by user namespaces, which allow unprivileged code to
exercise lots of root-only code paths and have lead to privilege
escalation vulnerabilities in the past.

We can safely leave user namespaces on for privileged users, as root
already has root privileges, but if you're not running builds on your
machine and really want to minimize the kernel attack surface then you
can set security.allowUserNamespaces to false.

Note that Chrome's sandbox requires either unprivileged CLONE_NEWUSER or
setuid, and Firefox's silently reduces the security level if it isn't
allowed (see about:support), so desktop users may want to set:

    boot.kernel.sysctl."kernel.unprivileged_userns_clone" = true;

a8989b353a Revert "nixos/hardened: build sandbox incompatible with namespaces"
As discussed in https://github.com/NixOS/nixpkgs/pull/73763, prevailing
consensus is to revert that commit. People use the hardened profile on
machines and run nix builds, and there's no good reason to use
unsandboxed builds at all unless you're in a platform that doesn't
support them.

This reverts commit 00ac71ab19.

docker-container: Remove /etc symlink
The system output usually contains a symlink from /etc to the static
configuration for the benefit of the stage-1 script in the initrd. The stage-2
script is usually started in the real root without such a symlink. In a
container, there is no stage-1 and the system output is used directly as a real
root. If the symlink is present, setup-etc.pl will create a symlink cycle and
the system cannot boot. There is no reason for the /etc link to exist in a
container because setup-etc.pl will create the necessary files. The container
module will now remove the /etc symlink and create an empty directory. The empty
/etc is for container managers to populate it with site-specific settings; for
example, to set the hostname. This is required to boot NixOS in an LXC container
on another host.

00ac71ab19 nixos/hardened: build sandbox incompatible with namespaces
Disables the build sandbox by default to avoid incompatibility with
defaulting user namespaces to false. Ideally there would be some kind of
linux kernel feature that allows us to trust nix-daemon builders to
allow both nix sandbox builds and disabling untrusted naemspaces at the
same time.
