Prometheus OpenVPN exporter has been broken since OpenVPN 2.5.0 changed
the format of the datetime to ISO8601. After submitting an issue to
upstream, the upstream decided to no longer maintain this exporter.
Recent updates to the bcachefs kernel resulted in a change in on-disk
format. However, since bcachefs-tools wasn't updated at the same time,
they became incompatible, causing a variety of issues. This brings the
linux-testing-bcachefs and bcachefs-tools versions back into sync.
Don't worry, it's is true by default. But I think this is important to
have because NixOS indeed shouldn't need Nix at run time when the
installation is not being modified, and now we can verify that.
NixOS images that cannot "self-modify" are a legitamate
use-case that this supports more minimally. One should be able to e.g. do a
sshfs mount and use `nixos-install` to modify them remotely, or just
discard them and build fresh ones if they are run VMs or something.
The next step would be to make generations optional, allowing just
baking `/etc` and friends rather than using activation scripts. But
that's more involved so I'm leaving it out.
I realized quite recently that running a test VM - as documented in the
manual - like
QEMU_NET_OPTS='hostfwd=tcp::8080-:80' ./result/bin/nixos-run-vms
doesn't work anymore on `master`. After bisecting I realized that the
introduction of a forward-port option[1] is the problem since it adds a
trailing comma even if no forwarding options are specified via
`virtualisation.forwardPorts`. In that case, the networking options
would look like `-netdev user,id=user.0,,hostfwd=tcp::8080-:80' which
confused QEMU and thus the VM refused to start.
Now, the trailing comma is only added if additional port forwards are
specified declaratively.

Summary:
- This new release internalizes the old, explicit log into `./build{,8}` scripts.
- Reduces closure size, by explicitly passing JDK(GraalVM) library output to native-image flags.
- Moves JDK to native build inputs.
- Resets meta.priority to default, since it is explicitly differentiated by pname.
