This means that all systems running from master will trigger
new certificate creation on next rebuild. Race conditions around
multiple account creation are fixed in #106857, not this commit.

Florian Klink d22b3ed4bc systemd: switch to unified cgroup hierarchy by default
See https://www.redhat.com/sysadmin/fedora-31-control-group-v2 for
details on why this is desirable, and how it impacts containers.

Users that need to keep using the old cgroup hierarchy can re-enable it
by setting `systemd.unifiedCgroupHierarchy` to `false`.

Well-known candidates not supporting that hierarchy, like docker and
hidepid=… will disable it automatically.

David Reiss 49a749c729 nixos/pam_mount: add pamMount attribute to users
This attribute is a generalized version of cryptHomeLuks for creating an
entry in /etc/security/pam_mount.conf.xml. It lets the configuration
control all the attributes of the <volume> entry, instead of just the
path. The default path remains the value of cryptHomeLuks, for
compatibility.

Fix the check to give a sensible assert message instead; the attribute

Jeroen Simonetti cc3ce9a13a nixos/security/acme: Add DNS resolver option
When using the ACME DNS-01 challenge, there is a possibility of a
failure to resolve the challenge if the record is not propagated
fast enough. To circumvent this generic DNS problem, this adds
a setting to explicitly tell the ACME provider to use a certain DNS
resolver to lookup the challenge.

Revert "apparmor: fix and improve the service"
This reverts commit fb6d63f3fd.

I really hope this finally fixes #99236: evaluation on Hydra.
This time I really did check basically the same commit on Hydra:
https://hydra.nixos.org/eval/1618011

Right now I don't have energy to find what exactly is wrong in the
commit, and it doesn't seem important in comparison to nixos-unstable
channel being stuck on a commit over one week old.

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.

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.

nicoo 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
