nixos-rebuild test causes pam_mount to prompt for a password when running with
an encrypted home:
building '/nix/store/p6bflh7n5zy2dql8l45mix9qnzq65hbk-nixos-system-mildred-18.09.git.98592c5da79M.drv'...

reenter password for pam_mount:

This change makes pam_mount not prompt. It still tries to remount (and fails in
the process) but that message can be ignored.
Fixes: #44586
Since 7a10478ea7, all /var except
/var/lib/acme gets mounted in a read-only fashion. This behavior
breaks the existing acme deployments having a webroot set outside of
/var/lib/acme.
Collecting the webroots and adding them to the paths read/write
mounted to the systemd service runtime tree.
Fixes #139310
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.
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.
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.
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.
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.
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.
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.)

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.
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.
First because IFD (import-from-derivation) is not allowed on hydra.nixos.org,
and second because without https://github.com/NixOS/hydra/pull/825
hydra-eval-jobs crashes instead of skipping aggregated jobs which fail
(here because they required an IFD).
