Move all `virtualisation.libvirtd.qemu*` options to a
`virtualisation.libvirtd.qemu` submodule.
Also for consistency, add `virtualisation.libvirtd.qemu.swtpm.package`
(only new option during this refactor.)
we need the file itself as a dependency for the docbook build, but we don't need
it to be properly sorted at the nix level. push the sort out to a python script
instead to save eval time. on the machine used to write this `nix-instantiate
<nixos/nixos> -A system` went down from 7.1s to 5.4s and GC heap size decreased
by 50MB (or 70MB max RSS).
The latest version of Subsonic (6.1.6) does not suport Java SE 9 or later
because it depends on the JAXB APIs. Those are considered to be Java EE
APIs are no longer contained on the default classpath in Java SE 9 and
are completely removed in Java SE 11..
This makes the order of operations the same in dry-activate and a "true"
activate. Also fixes the indentation I messed up and drop a useless
unlink() call (we are already unlinking that file earlier).
The previous logic failed to detect that units were socket-activated
when the socket was stopped before switch-to-configuration was run. This
commit fixes that and also starts the socket in question.
The first FIXME is removed because it doesn't make sense to use
/proc/1/exe since that points to a directory that doesn't have all tools
the activation script needs (like systemd-escape).
The second one is removed because there is already no error handling
(compare with the restart logic where the return code is checked).
This commit changes a lot more that you'd expect but it also adds a lot
of new testing code so nothing breaks in the future. The main change is
that sockets are now restarted when they change. The main reason for
the large amount of changes is the ability of activation scripts to
restart/reload units. This also works for socket-activated units now,
and honors reloadIfChanged and restartIfChanged. The two changes don't
really work without each other so they are done in the one large commit.
The test should show what works now and ensure it will continue to do so
in the future.
