Yes I know it's dirty to link the rendered HTML, but linking
`#sec-kernel-config` breaks the manual build for me with the following
error:
element link: validity error : IDREF attribute linkend references an unknown ID "sec-kernel-config"
This is something that should probably be fixed, but for the current
change I'd argue that this is good enough (in fact even the
`nix.settings`-option uses that hack).
When no interfaces are managed by systemd-networkd, it will
unconditionally fail. This option allows it to be disabled in those
situations where it prevents system switches from succeeding.
The placement of this option under `nix` was misleading, as it is not
configuration of the Nix daemon, but rather configuration of the NixOS
boot process and how it mounts the Nix store. As such, make it an option
of `boot` to clarify what it actually affects, and imply that it will
only take effect on a reboot.
Since it no longer has the context of nix, adjust the name to include
it.
Or else systemd-oomd gets marked as failed due to
"Userspace Out-Of-Memory (OOM) Killer was skipped because of a failed condition check (ConditionControlGroupController=v2)."
and cause the system to enter degraded state.

mountFS adds these strings to fstab and then relies on `mount` parsing fstab. If
they have spaces or tabs in them, that would break fstab and therefore not mount
with the unhelpful error: No such file or directory.

Replaces the `dhcpV6PrefixDelegationConfig` with
`dhcpPrefixDelegationConfig` and throws an error if the old option is
used.
Also adapt the respective IPv6 prefix delegation test.
Before this patch, the entry match condition always fails, causing all
entries being removed. The error is not noticed because later they are
re-generated.
Before this patch, the gen_number found by regex contains
"-specialisation-foo" if specialisation is used. As a result, applying
int() to gen_number raises ValueError, causing entries containing
a specialisation part not being removed.
