Add the option `environmentFile` to allow passing secrets to the service
without adding them to the Nix store, while keeping the current
configuration via the existing environment file intact.
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.

readd perl (used in shell scripts), rsync (needed for NixOps) and strace (common debugging tool)
they where previously removed in https://github.com/NixOS/nixpkgs/pull/91213

systemd-confinement's automatic package extraction does not work correctly
if ExecStarts ExecReload etc are lists.
Add an extra flatten to make things smooth.
Fixes#96840.
xss-lock needs XDG_SESSION_ID to respond to loginctl lock-session(s)
(and possibly other session operations such as idle hint management).
This change adds XDG_SESSION_ID to the list of imported environment
variables when starting systemctl.
Inspired by home-manager, add importVariables configuration.
Set session to XDG_SESSION_ID when running xss-lock as a service.

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
