Some specialisations (such as those which affect various boot-time
attributes) cannot be switched to at runtime. This allows picking the
specialisation at boot time.
Massively reduce the time it takes running the test by building a
proper root disk image and increasing the virtualized core count to
4. This should make it much easier for the tests to pass even on
weaker systems.
With my laptop (AMD Ryzen 7 PRO 2700U) as the reference system, I see
the following test run times:
- No change:
Times out after 28 mins
- Building a root image:
7 mins, 48 secs
- Building a root image and bumping the core count:
7 mins, 17 secs
The times include the time it takes to build the image
(~1 min, 20 secs).

With my laptop (AMD Ryzen 7 PRO 2700U, 32GB RAM) as the reference

4 mins, 44 secs

The times include the time it takes to build the image (~40 secs).
pathsInNixDB isn't a very accurate name when a Nix store image is
built (virtualisation.useNixStoreImage); rename it to additionalPaths,
which should be general enough to cover both cases.
The existing tests for HDFS and YARN only check if the services come up and expose their web interfaces.
The new combined hadoop test will also test whether the services and roles work together as intended.
It spin up an HDFS+YARN cluster and submit a demo YARN application that uses the hadoop cluster for
storageand yarn cluster for compute.
The version 20 of Nextcloud will be EOLed by the end of this month[1].
Since the recommended default (that didn't raise an eval-warning) on
21.05 was Nextcloud 21, this shouldn't affect too many people.
In order to ensure that nobody does a (not working) upgrade across
several major-versions of Nextcloud, I replaced the derivation of
`nextcloud20` with a `throw` that provides instructions how to proceed.
The only case that I consider "risky" is a setup upgraded from 21.05 (or
older) with a `system.stateVersion` <21.11 and with
`services.nextcloud.package` not explicitly declared in its config. To
avoid that, I also left the `else-if` for `stateVersion < 21.03` which
now sets `services.nextcloud.package` to `pkgs.nextcloud20` and thus
leads to an eval-error. This condition can be removed
as soon as 21.05 is EOL because then it's safe to assume that only
21.11. is used as stable release where no Nextcloud <=20 exists that can
lead to such an issue.
It can't be removed earlier because then every `system.stateVersion <
21.11` would lead to `nextcloud21` which is a problem if `nextcloud19`
is still used.
