This ensures that they're gone by the time the shutdown job runs, so
it doesn't have to stop them itself.
* Don't respawn tasks, as it doesn't seem useful (if they fail they're
likely to fail again if they're restarted).

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.

the current configuration don't match the running kernel. This
ensures that modprobe still works after a "nixos-rebuild switch" to
a configuration that has a different kernel version.

to the nixpkgs trunk 'kernelPackages'.
Seeing a strange kernelPackages mentioned in installation-cd-rescue (2.6.31_something) I
update that to 2.6.32.

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 (?)

pkgs/build-support/vm). This should make the NixOS regression tests
more robust on heavily loaded systems, where they now frequently
fail:
server# mounting //10.0.2.4/qemu on /hostfs...
server# [ 8.233991] Slow work thread pool: Starting up
server# [ 8.234721] Slow work thread pool: Ready

server# mount: Host is down
server# [ 23.275188] Kernel panic - not syncing: Attempted to kill init!
Maybe there is a configurable timeout somewhere, which would be much
nicer...

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.

/nix bind mounted from a fs not rootfs.
As niksnut found, if the sources of bind mounted directories are
umounted before remounting them as "ro", a "mount -o remount,ro" on the
bind targets will not leave the filesystem properly umounted, the same
way as a "-o remount,ro" would do on a usual filesystem.
So, the trick of always remounting as 'ro' before attempting an umount seems
to fix the problem.

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".

modules that should be added to the initrd, but should only be
loaded on demand (e.g. by the kernel or by udev). This is
especially useful in the installation CD, where we now only load the
modules needed by the hardware.
* Enable automatic modprobing by udev in the initrd.

automatically loaded by the kernel, load it at boot time.
* Put the ext2 module (which used to be built in) in the initrd to
prevent unexpected breakage.

This serves as example how to run a vm within a bulid job.
