nixos/security/acme: order after nss-lookup.target
This should hopefully solve races with DNS servers (such as unbound)
during the activation of a new generation. Previously unbound could
still be unavailable and thus the acme script would fail.

pam: Fix interaction with samba
9544c6078e12aacaf17abc9a13e740658b17e747 / #96672 removed the samba option
`syncPasswordsByPam`.
Need to remove this option from the pam module, otherwise it will cause build errors

nixos/sudo: add package option
The `package`-option is always useful if modifying a package in an
overlay would mean that a lot of other packages need to be rebuilt as
well.

In case of `sudo` this is actually the case: when having an override for
it (e.g. for `withInsults = true;`), you'd have to rebuild e.g. `zfs`
and `grub` although that's not strictly needed.

nixos/security/wrapper: ensure the tmpfs is not world writeable
The /run/wrapper directory is a tmpfs. Unfortunately, it's mounted with
its root directory has the standard (for tmpfs) mode: 1777 (world writeable,
sticky -- the standard mode of shared temporary directories). This means that
every user can create new files and subdirectories there, but can't
move/delete/rename files that belong to other users.

e64d3f60fb nixos/modules/security/rngd: Disable by default
`rngd` seems to be the root cause for slow boot issues, and its functionality is
redundant since kernel v3.17 (2014), which introduced a `krngd` task (in kernel
space) that takes care of pulling in data from hardware RNGs:

nixos/acme: Fix race condition, dont be smart with keys
Attempting to reuse keys on a basis different to the cert (AKA,
storing the key in a directory with a hashed name different to
the cert it is associated with) was ineffective since when
"lego run" is used it will ALWAYS generate a new key. This causes
issues when you revert changes since your "reused" key will not
be the one associated with the old cert. As such, I tore out the
whole keyDir implementation.

As for the race condition, checking the mtime of the cert file
was not sufficient to detect changes. In testing, selfsigned
and full certs could be generated/installed within 1 second of
each other. cmp is now used instead.

Also, I removed the nginx/httpd reload waiters in favour of
simple retry logic for the curl-based tests

nixos/acme: Restructure module
- Use an acme user and group, allow group override only
- Use hashes to determine when certs actually need to regenerate
- Avoid running lego more than necessary
- Harden permissions
- Support "systemctl clean" for cert regeneration
- Support reuse of keys between some configuration changes
- Permissions fix services solves for previously root owned certs
- Add a note about multiple account creation and emails
- Migrate extraDomains to a list
- Deprecate user option
- Use minica for self-signed certs
- Rewrite all tests

I thought of a few more cases where things may go wrong,
and added tests to cover them. In particular, the web server
reload services were depending on the target - which stays alive,
meaning that the renewal timer wouldn't be triggering a reload
and old certs would stay on the web servers.

I encountered some problems ensuring that the reload took place
without accidently triggering it as part of the test. The sync
commands I added ended up being essential and I'm not sure why,
it seems like either node.succeed ends too early or there's an
oddity of the vm's filesystem I'm not aware of.

- Fix duplicate systemd rules on reload services

Since useACMEHost is not unique to every vhost, if one cert
was reused many times it would create duplicate entries in
${server}-config-reload.service for wants, before and

apparmor: add apparmor_parser config file
If the config does not exist, then apparmor_parser will throw a warning.
To avoid that and make the parser configurable, we now add a new option
to it.

962e15aebc nixos: remove StandardOutput=syslog, StandardError=syslog lines
Since systemd 243, docs were already steering users towards using
`journal`:

eedaf7f322

systemd 246 will go one step further, it shows warnings for these units
during bootup, and will [automatically convert these occurences to
`journal`](f3dc6af20f):

> [    6.955976] systemd[1]: /nix/store/hwyfgbwg804vmr92fxc1vkmqfq2k9s17-unit-display-manager.service/display-manager.service:27: Standard output type syslog is obsolete, automatically updating to journal. Please update│······················
 your unit file, and consider removing the setting altogether.

So there's no point of keeping `syslog` here, and it's probably a better
idea to just not set it, due to:

> This setting defaults to the value set with DefaultStandardOutput= in
> systemd-system.conf(5), which defaults to journal.

nixos/sudo: default rule should be first
In /etc/sudoers, the last-matched rule will override all

66e040eaac nixos/pam: mount encrypted home earlier
This patch was done by curro:

The generated /etc/pam.d/* service files invoke the pam_systemd.so
session module before pam_mount.so, if both are enabled (e.g. via
security.pam.services.foo.startSession and
security.pam.services.foo.pamMount respectively).

This doesn't work in the most common scenario where the user's home
directory is stored in a pam-mounted encrypted volume (because systemd
will fail to access the user's systemd configuration).

nixos/doas: init
`doas` is a lighter alternative to `sudo` that "provide[s] 95% of the
features of `sudo` with a fraction of the codebase" [1]. I prefer it to
`sudo`, so I figured I would add a NixOS module in order for it to be
easier to use. The module is based off of the existing `sudo` module.
