nixosTests.installer: Fix grub1 test being unreliable The kernel sometimes assigns `/dev/sdb` to the 8GiB disk.

nixos/nix-daemon: use structural settings The `nix.*` options, apart from options for setting up the daemon itself, currently provide a lot of setting mappings for the Nix daemon configuration. The scope of the mapping yields convience, but the line where an option is considered essential is blurry. For instance, the `extra-sandbox-paths` mapping is provided without its primary consumer, and the corresponding `sandbox-paths` option is also not mapped. The current system increases the maintenance burden as maintainers have to closely follow upstream changes. In this case, there are two state versions of Nix which have to be maintained collectively, with different options avaliable. This commit aims to following the standard outlined in RFC 42[1] to implement a structural setting pattern. The Nix configuration is encoded at its core as key-value pairs which maps nicely to attribute sets, making it feasible to express in the Nix language itself. Some existing options are kept such as `buildMachines` and `registry` which present a simplified interface to managing the respective settings. The interface is exposed as `nix.settings`. Legacy configurations are mapped to their corresponding options under `nix.settings` for backwards compatibility. Various options settings in other nixos modules and relevant tests have been updated to use structural setting for consistency. The generation and validation of the configration file has been modified to use `writeTextFile` instead of `runCommand` for clarity. Note that validation is now mandatory as strict checking of options has been pushed down to the derivation level due to freeformType consuming unmatched options. Furthermore, validation can not occur when cross-compiling due to current limitations. A new option `publicHostKey` was added to the `buildMachines` submodule corresponding to the base64 encoded public host key settings exposed in the builder syntax. The build machine generation was subsequently rewritten to use `concatStringsSep` for better performance by grouping concatenations.

nixos/tests/installer: Add test for LUKS rootfs. This serves as a regression test for #7859. It's pretty straightforward, except from the fact that nixos-generate- config doesn't detect LUKS devices and the "sleep 60". As for the former, I have tried to add support for LUKS devices for nixos-generate-config, but it's not so easy as it sounds, because we need to create a device tree across all possible mappers and/or LVM up to the "real" device and then decide whether it is relevant to what is currently mounted. So I guess this is something for the nixpart branch (see #2079). And the latter isn't very trivial as well, because the LUKS passphrase prompt is issued on /dev/console, which is the last "console=..." kernel parameter (thus the `mkAfter`). So we can't simply grep the log, because the prompt ends up being on one terminal only (tty0) and using select() on $machine->{socket} doesn't work very well, because the FD is always "ready for read". If we would read the FD, we would conflict with $machine->connect and end up having an inconsistent state. Another idea would be to use multithreading to do $machine->connect while feeding the passphrase prompt in a loop and stop the thread once $machine->connect is done. Turns out that this is not so easy as well, because the threads need to share the $machine object and of course need to do properly locking. In the end I decided to use the "blindly hope that 60 seconds is enough" approach for now and come up with a better solution later. Other VM tests surely use sleep as well, but it's $machine->sleep, which is bound to the clock of the VM, so if the build machine is on high load, a $machine->sleep gets properly delayed but the timer outside the VM won't get that delay, so the test is not deterministic. Tested against the following revisions: 5e3fe39: Before the libgcrypt cleanup (a71f78a) that broke cryptsetup. 69a6848: While cryptsetup was broken (obviously the test failed). 15faa43: After cryptsetup has been switched to OpenSSL (fd588f9).
