systemd-nspawn can react to SIGTERM and send a shutdown signal to the container
init process. use that instead of going through dbus and machined to request
nspawn sending the signal, since during host shutdown machined or dbus may have
gone away by the point a container unit is stopped.
to solve the issue that a container that is still starting cannot be stopped
cleanly we must also handle this signal in containerInit/stage-2.
At the moment, it's not possible to override the libvirtd package used
without supplying a nixpkgs overlay. Adding a package option makes
libvirtd more consistent and allows enabling e.g. ceph and iSCSI support
more easily.
Xen is now enabled unconditionally on kernels that support it, so the
xen_dom0 feature doesn't do anything. The isXen attribute will now
produce a deprecation warning and unconditionally return true.
Passing in a custom value for isXen is no longer supported.
This dependency has been added in 65eae4d, when NixOS switched to
systemd, as a substitute for the previous udevtrigger and hasn't been
touched since. It's probably unneeded as the upstream unit[1] doesn't
do it and I haven't found any mention of any problem in NixOS or the
upstream issue trackers.

Related to #85746 which addresses documentation issue,
digging deeper for a reason why this was disabled
was simply because it wasn't working which is not the case anymore.
- Actually use the zfsSupport option
- Add documentation URI to lxd.service
- Add lxd.socket to enable socket activatation
- Add proper dependencies and remove systemd-udev-settle from lxd.service
- Set up /var/lib/lxc/rootfs using systemd.tmpfiles
- Configure safe start and shutdown of lxd.service
- Configure restart on failures of lxd.service
Launching a container with a private network requires creating a
dedicated networking interface for it; name of that interface is derived
from the container name itself - e.g. a container named `foo` gets
attached to an interface named `ve-foo`.
An interface name can span up to IFNAMSIZ characters, which means that a
container name must contain at most IFNAMSIZ - 3 - 1 = 11 characters;
it's a limit that we validate using a build-time assertion.
This limit has been upgraded with Linux 5.8, as it allows for an
interface to contain a so-called altname, which can be much longer,
while remaining treated as a first-class citizen.
Since altnames have been supported natively by systemd for a while now,
due diligence on our side ends with dropping the name-assertion on newer
kernels.

Ensure that the HyperV keyboard driver is available in the early
stages of the boot process. This allows the user to enter a disk
encryption passphrase or repair a boot problem in an interactive
shell.
We now set the hooks dir correctly if the OCI hook is enabled. CRI-O
supports this specific hook from v1.20.0.
