be used on HVM instances without needing nixops. Previously the grub setup was incorrect, so a plain 'nixos-rebuild switch' and a reboot would result in a broken system. Also added growing of the partition of the root disk in the initrd, so you can run resize2fs after initial boot, without needing an extra reboot. This is useful especially for nixops' deployment.ec2.ebsInitialRootDiskSize option.
