FIXME(@bpeetz):
This results in a boot error, as the `/var/lib/sshd` directory
is only mounted _after_ the stage 2 init and with it the system
activation. `agenix` needs the sshd hostkey however to decrypt the
secrets and thus we have to ensure that this directory is mounted
_before_ the system activation. Alas the only way I see to achieve
that is to store the ssh hostkey directly on /srv, which is mounted
before (it's marked as 'neededForBoot' after all).
It should be possible to achieve this with impermanence however,
as `/var/log` is mounted in the stage 1 init; The problem is that
I have no idea _why_ only this is mounted and nothing else.
vhack.persist.directories = [
{
directory = "/var/lib/sshd";
user = "root";
group = "root";
mode = "0755";
}
