After the change from revision 30103, nixos-rebuild suddenly consumed
freaky amounts of memory. I had to abort the process after it had
allocated well in excess of 30GB(!) of RAM. I'm not sure what is causing
this behavior, but undoing that assignment fixes the problem. The other
two commits needed to be revoked, too, because they depend on 30103.

that udevd passes its own environment variables, but this is not the
case.)

problem is that configuration values below a mkIf are evaluated
strictly even if the condition is false. Thus "${luksRoot}" causes
an evaluation error. As a workaround, use the empty string instead
of `null' as the default value. However, we should really fix the
laziness of mkIf. It's likely that NixOS evaluation would be much
faster if it didn't have to evaluate disabled configuration values.

init script. This removes the need for the `systemConfig' boot
parameter; `init=<stage-2-init>' is enough. However, the GRUB menu
builder still needs to add `systemConfig' to the kernel command line
for compatibility with old configurations.

* Moved some scriptlets to the appropriate modules.
* Put the scriptlet that sets the default path at the start, since it
never makes sense not to have it there. It no longer needs to be
declared as a dependency.
* If a scriptlet has no dependencies, it can be denoted as a plain
string (i.e., `noDepEntry' is not needed anymore).

build hook uses this directory to store temporary GC roots. (It
creates it if it doesn't exist, but it's better to do it here as
well to ensure the right ownership and permissions.)
* Clear /nix/var/nix/gcroots/tmp and /nix/var/nix/temproots at boot
time.

root=... kernel command line parameter, instead of hard-coding it in

UNetbootin to rewrite the kernel command line to the label or UUID
of the USB stick.

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)").

As a result, `cdrom_id' doesn't print
ID_CDROM_MEDIA_TRACK_COUNT_DATA, which in turn prevents the
/dev/disk/by-label symlinks from being created. We need these in
the NixOS installation CD, so use ID_CDROM_MEDIA in the
corresponding udev rules for now. This was the behaviour in udev <=
154. See also

shutdown. (Portmap and statd are needed during shutdown to unmount
NFS volumes but have open files in /var/run.)
* In the shutdown job, don't kill PIDs belonging to Upstart jobs that
are still running. If they don't stop on the "starting shutdown"
event, then they're needed during shutdown (such as portmap and
statd).
* NFS test: test whether the shutdown quickly unmounts NFS volumes
(i.e. whether portmap and statd are still running).

to use the standard (coreutils) tools.
* Use util-linux's `switch_root' to switch over to the target root
FS. It automatically moves over the /dev, /proc and /sys from stage
1, so stage 2 doesn't need to set them up again.

By default, they take the usual value of "50% of physical RAM".
As /dev/shm can be filled by anyone, and tmpfs does not trigger the OOM killer (and
can hang the machine due to a lack of RAM), I need to configure that down
in order to avoid crashes.
There is still left the /var/run/nscd tmpfs filesystem, also created with 50%
of the RAM, but at least not writeable by anyone. We could find a reasonable
low value for that, or allow configuration.

readd r19267 (the issue should be fixed now)
Eelco Dolstra and Nicolas Pierron both kept asking me to pay attention
to the rendered manual. There is one catch: example settings such as
pkgs.kernelPackages_2_6_25 are correct however they don't render
properly. Moreover you don't want those examples to be evaluated (maybe
compiling a kernel ?) when building the manual only.
So use Strings and add a copy & paste note.
This is still a hacky. Maybe a kind of typed "verbatim" expression
should be added (?)

more robust on heavily loaded systems, where they now frequently

write some magic string to ttyS0. This removes the dependency on
having a CIFS mount.
* Use a thread to process the stdout/stderr of each QEMU instance.
* Add a kernel command line parameter "stage1panic" to tell stage 1 to
panic if an error occurs. This is faster than waiting until
connect() times out.

modules that should be added to the initrd, but should only be

no longer emits specific events for those. Instead it emits a
"runlevel" event. The "runlevel" task starts the "shutdown" task to
perform the desired action.
* Upstart 0.6 no longer has a "shutdown" event, so "stop on shutdown"
no longer works. Therefore the shutdown task explicitly stops all
running Upstart jobs, before sending a TERM/KILL signal to all
remaining processes.
* Do a "chvt 1" at the start of the shutdown task to switch to the
console.
* Use /dev/console instead of /dev/tty1, since if somebody is logged
in on tty1, bad things will happen.

suddenly happens. Probably because of the nixpkgs.config change,
but I don't see why. Maybe the option evaluation is too strict.
