The ability to specify "-drive if=scsi" has been removed in QEMU version
2.12 (introduced in 3e3b39f173).

So whenever the diskInterface is "scsi" we use the new way to specify
the drive and fall back to the deprecated way for the time being. The
reason why I'm not using the new way for "virtio" and "ide" as well is
because there is no simple generic way anymore to specify these.
This also turns the type of the virtualisation.qemu.diskInterface option
to be an enum, so the user knows which values are allowed but we can
also make sure the right value is provided to prevent typos.
I've tested this against a few non-disk-related NixOS VM tests but also
the installer.grub1 test (because it uses "ide" as its drive interface),
the installer.simple test (just to be sure it still works with
"virtio") and all the tests in nixos/tests/boot.nix.
In order to be able to run the grub1 test I had to go back to
8b1cf100cd (which is a known commit where
that test still works) and apply the QEMU update and this very commit,
because right now the test is broken.
Apart from the tests here in nixpkgs, I also ran another[1] test in
another repository which uses the "scsi" disk interface as well (in
comparison to most of the installer tests, this one actually failed
prior to this commit).
All of them now succeed.

The usb_add and usb_del monitor commands have been removed in QEMU
version 2.12 (introduced in 3e3b39f173).

So we're doing exactly that and the udisks2 test now works again.

I'm not sure why 024b501907 used -q 0
because even netcat-openbsd has the -N flag which IMO is the better way
to shutdown the socket on EOF.
Our default netcat implementation has changed once again[1] in
3c3b82234a and we're now using LibreSSL's
implementation, which doesn't have a -q flag.
See https://github.com/NixOS/nixpkgs/pull/39634 for the pull request
introducing the switch.

The Nix expression here is really hard to read with multiple (and
unnecessarily) nested lets and it also generates attribute names based
on the derivation generated by makeTest, which will result in these
attribute names:
* vm-test-run-predictableInterfaceNames
* vm-test-run-predictableInterfaceNames-with-networkd
* vm-test-run-unpredictableInterfaceNames
* vm-test-run-unpredictableInterfaceNames-with-networkd
With the refactor the attribute names are now:
* predictable
* predictableNetworkd
* unpredictable
* unpredictableNetworkd
So now the code is even shorter and IMHO slightly more readable.

This is a very very very ugly workaround and it's because Chromium seems
to eat keystroke for a few seconds after a new window is created.
I haven't found a better solution yet, so let's at least unbreak the
test until we come up with a better way.
Thanks to @vcunat for bringing this to my attention and also doing the
initial bisect.
The change that brought up this problem was 2b29e40153,
which updated Chromium from version 65.0.3325.181 to version
66.0.3359.117. Unfortunately the upstream changelog[1] is way too large
to actually guess what the breaking change is.

mke2fs has this annoying property that it uses getrandom() to get random
numbers (for whatever purposes) which blocks until the kernel's secure
RNG has sufficient entropy, which it usually doesn't in the early boot
(except if your CPU supports RDRAND) where we may need to create the
root disk.
So let's give the VM a virtio RNG to avoid the boot getting stuck at
mke2fs.
Ubiquiti has both a LTS and current version of their Unifi controller software.
The latter adds new features, but may drop support for some devices.
This adds the capability to use either for the unifi module but defaults
to the LTS version, which was the previous behavior.
Previously we indirectly suggested that the user use
services.printing.extraConf to set this, but this doesn't work with the
default merge ordering. Fix this by making it an independent option.
Fixes#39611.
@cleverca found this bug in the declarative hooks config. Any shell
variables referenced in a hook script would get expanded by the hooks
directory builder.
Prevent variable expansion by quoting the here doc limit string.
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

xdotool failed in rare cases when a window was already created
but not yet decorated by the window manager.
