This introduces a dependency on xxHash. Unfortunately, hashcat's
build system wants to rebuild xxHash from the source code located
in `<hashcat source root>/deps/git/xxHash`, a Git submodule whose
contents are not included in the source tarball we currently
download.
This could be fixed by either using a recursive git clone instead
a tarball download, or patching the build files to use an existing
installation of xxHash (i.e. the one already provided by Nix). I
believe the latter is preferable since it avoids the situation in
which the xxHash version used by hashcat is different to the xxHash
version used by all other Nix packages.
Fortunately, this situation has been greatly improved [1] since
release 5.0.0; the next release of hashcat should drop usage of
git submodules and provide better support for using existing
installations of dependencies.

Cloudstack images are simply using cloud-init. They are not headless
as a user usually have access to a console. Otherwise, the difference
with Openstack are mostly handled by cloud-init.
This is still some minor issues. Notably, there is no non-root user.
Other cloud images usually come with a user named after the
distribution and with sudo. Would it make sense for NixOS?
Cloudstack gives the user the ability to change the password.
Cloud-init support for this is imperfect and the set-passwords module
should be declared as `- [set-passwords, always]` for this to work. I
don't know if there is an easy way to "patch" default cloud-init
configuration. However, without a non-root user, this is of no use.
Similarly, hostname is usually set through cloud-init using
`set_hostname` and `update_hostname` modules. While the patch to
declare nixos to cloud-init contains some code to set hostname, the
previously mentioned modules are not enabled.
It's a quick approximation to unblock unstable channels after #48116.
This commit isn't ideal, as I suspect most wayland users won't have
xserver.enable, so they will lose the icon cache in case they had gtk
in system path (otherwise they didn't get cache anyway).
I considered using environment.noXlibs, but the nixos tests installing
headless systems do *not* get that option, so we would still be pulling
gtk in many cases where it's clearly not desired. We need to design
this more carefully.
