This has shown to be flaky in the VM test, at least when running on
the aarch64 ofborg builder(s).
I assume it's some flakyness in systemd-networkd not being fully up, or
at least not up to the point that it properly replies to the _gateway
request.
This part of the test is supposed to test external (non-glibc) nss
module lookup for the host database works, which is already sufficiently
covered in the previous checks (for *.localhost). Drop these redundant
checks. We're not integration-testing networkd here.
Configures the `--cache-dir` parameter for the prune and check commands run after backing up. For `check`, also adds a `checkOpts` flag to enable using the cache, since that is disabled by default.
Build will start failing with the following error in 2.55.1 due to `/build/librsvg-2.55.1/.libs` ending up in rpath:
RPATH of binary /nix/store/78k70limslvxs6y98hdirbcixl3car1q-librsvg-2.55.1-installedTests/libexec/installed-tests/RSVG/api contains a forbidden reference to /build/
With the announced EOL of the venerable ISC DHCP Server it is time to
migrate this test to Kea, it's successor.
The ISP has also received an upgrade to its interface configuration,
which now happens completely through networkd.

*Flags implies a list
slightly relevant:
> stdenv: start deprecating non-list configureFlags https://github.com/NixOS/nixpkgs/pull/173172
the makeInstalledTests function in `nixos/tests/installed-tests/default.nix` isn't available outside of nixpkgs so
it's not a breaking change
Adapt to changes introduced in Systemd 250:
> The [DHCPv6PrefixDelegation] section in .network file is renamed to
> [DHCPPrefixDelegation], as now the prefix delegation is also
> supported with DHCPv4 protocol by enabling the Use6RD= setting.
Replaces the `dhcpV6PrefixDelegationConfig` with
`dhcpPrefixDelegationConfig` and throws an error if the old option is
used.
Also adapt the respective IPv6 prefix delegation test.
nixosTests.systemd is quite heavy, it requires a full graphical system,
which is quite a big of a rebuild if the only thing you want to test is
whether dynamic users work.
This is now moved to an `nscd` test, which tests various NSS lookups,
making extra sure that the nscd path is tested, not the fallback path
(by hiding /etc/nsswitch.conf and /etc/hosts for getent).
nixosTests.resolv is removed. It didn't check for reverse lookups,
didn't catch nscd breaking halfway in between, and also had an
ambiguous reverse lookup - 192.0.2.1 could either reverse lookup to
host-ipv4.example.net, or host-dual.example.net.
