nixos/lock-kernel-modules: reorder before/after
Moving the service before multi-user.target (so the `hardened` test
continue to work the way it did before) can result in locking the kernel
too early. It's better to lock it a bit later and changing the test to
wait specifically for the disable-kernel-module-loading.service.

nixos/lock-kernel-modules: use udevadm settle
Instead of relying on systemd-udev-settle, which is deprecated,
directly call `udevamd settle` to wait for hardware to settle.

nixos: explicitely set security.wrappers ownership
This is slightly more verbose and inconvenient, but it forces you
to think about what the wrapper ownership and permissions will be.

nixos/security/wrappers: check that sources exist
Add a shell script that checks if the paths of all wrapped programs
actually exist to catch mistakes. This only checks for Nix store paths,
which are always expected to exist at build time.

nixos/security/wrappers: use fixed defaults
To keep backward compatibility and have a typing would require making
all options null by default, adding a defaultText containing the actual
value, write the default value logic based on `!= null` and replacing
the nulls laters. This pretty much defeats the point of having used
a submodule type.

nixos/security/wrappers: make well-typed
The security.wrappers option is morally a set of submodules but it's
actually (un)typed as a generic attribute set. This is bad for several
reasons:

1. Some of the "submodule" option are not document;
2. the default values are not documented and are chosen based on
   somewhat bizarre rules (issue #23217);
3. It's not possible to override an existing wrapper due to the
   dumb types.attrs.merge strategy;
4. It's easy to make mistakes that will go unnoticed, which is
   really bad given the sensitivity of this module (issue #47839).

This makes the option a proper set of submodule and add strict types and
descriptions to every sub-option. Considering it's not yet clear if the
way the default values are picked is intended, this reproduces the current
behavior, but it's now documented explicitly.

1645acf1d3 nixos: reduce pam files rebuilds on updates
Before whenever environment variables changed, pam files had to be
rebuild.

This is expensive since each file needs its own sandbox set up.

nixos/systemd-confinment: use /var/empty as chroot mountpoint
bind mounting directories into the nix-store breaks nix commands.
In particular it introduces character devices that are not supported
by nix-store as valid files in the nix store. Use `/var/empty` instead
which is designated for these kind of use cases. We won't create any
files beause of the tmpfs mounted.

nixos/acme: don't use --reuse-key
Reusing the same private/public key on renewal has two issues:

 - some providers don't accept to sign the same public key
   again (Buypass Go SSL)

 - keeping the same private key forever partly defeats the purpose of
   renewing the certificate often

Therefore, let's remove this option. People wanting to keep the same
key can set extraLegoRenewFlags to `[ --reuse-key ]` to keep the
previous behavior. Alternatively, we could put this as an option whose
default value is true.

348858f297 nixos/security.pki: handle PEMs w/o a final newline
According to the ABNF grammar for PEM files described in [RFC
7468][1], an eol character (i.e. a newline) is not mandatory after the
posteb line (i.e. "-----END CERTIFICATE-----" in the case of
certificates).

This commit makes our CA certificate bundler expression account for
the possibility that files in config.security.pki.certificateFiles
might not have final newlines, by using `awk` instead of `cat` to
concatenate them. (`awk` prints a final newline from each input file
even if the file doesn't end with a newline.)

083aba4f83 nixos/acme: Ensure certs are always protected
As per #121293, I ensured the UMask is set correctly
and removed any unnecessary chmod/chown/chgrp commands.
The test suite already partially covered permissions
checking but I added an extra check for the selfsigned
cert permissions.

nixos/pam: prioritize safer auth methods over fingerprints
Currently if fprintd is enabled, pam will ask for fingerprint
regardless of other configured authentication modules (e.g. yubikey).

This change make fingerprint the last resort of authentication before asking for password.

920a3f5a9d nixos/acme: Fix webroot issues
With the UMask set to 0023, the
mkdir -p command which creates the webroot
could end up unreadable if the web server
changes, as surfaced by the test suite in #114751
On top of this, the following commands
to chown the webroot + subdirectories was
mostly unnecessary. I stripped it back to
only fix the deepest part of the directory,
resolving #115976, and reintroduced a
human readable error message.
