...for explicitly named network interfaces
This reverts commit 6ae3e7695e.
(and evaluation fixups 08d26bbb727aed90a969)
Some of the tests fail or time out after the merge.
Adds a new option to the virtualisation modules that enables specifying
explicitly named network interfaces in QEMU VMs. The existing
`virtualisation.vlans` is still supported for cases where the name of
the network interface is irrelevant.
The aarch64-linux kernel and initrd recently eclipsed 60M, causing the
boot disk image build to run out of space and fail. Double the size of
the image to 120M to fix the issue.
The disk image is stored in expandable qcow2 format, so only the space
actually used by files in the image is consumed. Therefore, other
architectures are not unfairly penalized, and the output size does not
suddenly double.
This also fixes NixOS tests which use this option, like systemd-boot's.
The agent has not been updated for a very long time. In addition to
updating to the newest tagged version the change creates a package for
it.
The existing version has issues with the new python2.7 package not
containing crypt.so file. And the commit
6910a4eea0 I believe introduced
regression that caused the shebang to not be updated.
This adds a new ``parallelShutdown`` option that allows users to control
how many guests can be shut down concurrently. Allowing multiple virtual
machines to be shut down at the same time reduces the amount of time it
takes to reboot the host.

This fixes `lxd init`, which previously failed like this:
$ yes "" | lxd init
[...]

Add a section on ordering option definitions.
Also mention `mkDefault` in the section on `mkOverride`.
Clarify the code a bit by renaming `defaultPriority` to
`defaultOverridePriority` and introducing `defaultOrderPriority`.
We don't need both wget and curl, so let's use only curl (which is
part of a minimal NixOS closure, unlike wget).
Logging to the console is helpful for debugging.
Instances without SSH keys configured will receive a 404 from the
metadata server when attempting to fetch an SSH key. This is not an
actual problem though, and shouldn't result in the service failing.
If the metadata server cannot be reached, the script will fail at an
earlier stage when attempting to get authentication data.
This also removes automatic enablement/mounting of instance store swap
devices and ext3 filesystems. This behaviour is strongly opinionated
and shouldn't be enabled by default.
The unionfs behaviour never took effect anyway, because the AMI
manifest path only exists for instance store-backed AMIs, which have
not been supported by nixpkgs since
84742e2293 (2019).
