Fixes error
Can't use an undefined value as an ARRAY reference at /nix/store/...-install-grub.pl line 642, <FILE> line 5.
with `/boot/grub/state` being:
```
grub
2.04
no
/dev/sda
/boot
```
I am not sure where the trailing empty line can come from; the script does not
seem to write it. In any case, now we handle that situation as well.
Further, ensure that `extraGrubInstallArgs` defaults to the empty array
if its key is not present in the `jsonState`.
For example, turns the error
cannot copy /nix/store/g24xsmmsz46hzi6whv7qwwn17myn3jfq-grub-2.04/share/grub/unicode.pf2 to /boot
into the more useful
cannot copy /nix/store/g24xsmmsz46hzi6whv7qwwn17myn3jfq-grub-2.04/share/grub/unicode.pf2 to /boot: Read-only file system
Useful for when you need to build grub modules into your grub kernel
to get a working boot, as shown in the added example.
To store this new value, we switch to more structural JSON approach.
Using one line per value to store in `/boot/grub/state` gets really messy when
the values are arrays, or even worse, can contain newlines (escaping would be
needed). Further, removing a value from the file would get extra messy
(empty lines we'd have to keep for backwards compatibility).
Thus, from now on we use JSON to store all values we'll need in the future.
Without this, systemd-boot does not add an EFI boot entry for itself.
The reason it worked before this fix is because it would fall back to
the default installed \EFI\BOOT\BOOTX64.EFI
`sslCACert` was used for trust store of client and server certificates. Since `smtpd_tls_ask_ccert` defaults to no the setup of `smtpd_tls_CApath` was removed.
>By default (see smtpd_tls_ask_ccert), client certificates are not requested, and smtpd_tls_CApath should remain empty.

boot.loader.grub.device` was hardcoded to `bootDevice`, which is
wrong, because that's the device for `/`, and with `useBootLoader`
the boot loader is not on that device.
This bug probably came into existence because of bad naming;
`virtualisation.bootDevice` has description
"The disk to be used for the root filesystem", which is very confusing;
it should be `.rootDevice` then!
Unfortunately, the description is right and the attribute name is wrong,
so it is not easy to change this without deprecation.
This commit ensures that even if you use `useBootLoader` and
`diskInterface == "scsi"`, the created VM can boot through, and can run
`nixos-rebuild afterwards.
It also adds extra commentary to explain what's going on in this module
in general in relation to `useBootLoader`.
This explanation was contained in the description of
security.initialRootPassword but got lost when it was deprecated
a long ago (f496c3c) and removed.
This option has been deprecated for a long time because is redundant
(users.users.root.initialHashedPassword exists).
Moreover, being of type string, it required to handle the special value
"!" separately, instead of using just `null`.
This explains the
# Allow the user to log in as root without a password.
users.users.root.initialHashedPassword = "";
that the NixOS installer live systems use in
`profiles/installation-device.nix`.
Currently the service doesn't detect if on of the packages is updated
and doesn't restart.
By manually adding a trigger we make sure the service restarts if any of
the involved packages update.
In certain cases, for example when custom OpenLDAP modules are
compiled into the binary, users may want to override the package used
for OpenLDAP.
This is especially common in setups where LDAP is the primary
authentication source, as good password hashing mechanisms need to be
enabled as extra modules.
nixos/tests/initrd-openvpn: Add test for openvpn in the initramfs
The module in this commit adds new options that allows the
integration of an OpenVPN client into the initrd.
This can be used e.g. to remotely unlock LUKS devices.
This commit also adds two tests for `boot.initrd.network.openvpn`.
The first one is a basic test to validate that a failing connection
does not prevent the machine from booting.
The second test validates that this module actually creates a valid
openvpn connection.
For this, it spawns three nodes:
- The client that uses boot.initrd.network.openvpn
- An OpenVPN server that acts as gateway and forwards a port
to the client
- A node that is external to the OpenVPN network
The client connects to the OpenVPN server and spawns a netcat instance
that echos a value to every client.
Afterwards, the external node checks if it receives this value over the
forwarded port on the OpenVPN gateway.
We remove the configFile build flag override in the NixOS module.
Instead of embedding the conf file link to the binaries, we symlink it
to /etc/nsd/nsd.nix, the hardcoded config file location for the
various CLI nsd utilities.
This config file build option override is triggerring a nsd rebuild
for each configuration change. This prevent us to use the nixos cache
in many cases.

This can be used to explicitly specify a specific dtb file, relative to
the dtb base.
Update the generic-extlinux-compatible module to make use of this option.
Some bootloaders might not properly detect the model.
If the specific model is known by configuration, provide a way to
explicitly point to a specific dtb in the extlinux.conf.
