longer compares the current configuration to the previous
configuration, but instead compares the current Upstart state to the
intended state. Thus, if the switch script is interrupted, running
nixos-rebuild again will resume starting/stopping Upstart jobs where
the previous run left off.
We determine if an Upstart job has changed by having the pre-start
script of each Upstart job put a symlink to its .conf file in
/var/run/upstart-jobs. So if this symlink differs from the target
of /etc/init/<job>.conf, then the job has changed. This also
prevents multiple restarts of dependent jobs. E.g., if job B has
"start on started A" and "stop on stopping A", then restarting A
will cause B to be restarted, so B shouldn't B restarted a second
time.
We only start jobs that are not running if 1) they're tasks that
have been previously run (like mountall); or 2) they're jobs that
have a "start on" condition. This seems a reasonable heuristic.

like `build-vm', but boots using the regular boot loader (i.e. GRUB
1 or 2) rather than booting directly from the kernel/initrd. Thus
it allows testing of GRUB.

we want to generate the GRUB menu without actually installing GRUB
(because Amazon supplies its own pv-grub), and each menu entry
requires "root (hd0)". For the first, allow boot.loader.grub.device
to be set to "nodev" to indicate that the GRUB menu should be
generated without installing GRUB. For the second, add an option
boot.loader.grub.extraPerEntryConfig to allow commands to be added
to each GRUB menu entry (in this case, "root (hd0)").

screws up the X server (CPU usage goes to 100%, switching virtual
consoles no longer works, etc.). TODO: we need some generic way to
mark jobs that shouldn't be started automatically.

GRUB version changes. (That's the complete version from the name
attribute, not the boot.loader.grub.version attribute.) The current
version is recorded in /boot/grub/version. This is required to
prevent massive breakage when we change the default value of
boot.loader.grub.version to "2".

grub. Its options are no more inside 'boot', but inside 'boot.loader.grub'.
I added a new bootloader configuration for nixos, generationsDir. It creates
/boot/default/{init,initrd,kernel,system} symlinks, and the same for the generations
in /boot/system-$gen/{init,initrd,kernel,system}.
I can program the u-boot loader to load /boot/default files always, and have
a minimal nixos boot loader installer functionality. Additionally, I can refer
to the other system generations easily, with a simple 'ls' in /boot.

couldn't think of a better name). The top-level derivation is
returned in config.system.build.system.
* Inlined system.sh in top-level.nix so that we don't have to pass
everything through environment variables.
