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:

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 needed by the hardware.

unmounted or at least remounted read-only during shutdown. Upstart
0.6 apparently uses nscd to do some name lookups, resulting in it
holding some mmap mappings to deleted files in /var/run/nscd.
E.g. lsof shows:
init 1 root DEL REG 253,0 1850313 /var/run/nscd/dbyn3Piz
init 1 root DEL REG 253,0 1850312 /var/run/nscd/dbt2e8PH
See also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=324900.
This is a workaround - it would be better if Upstart didn't do this.

statically configured interface (i.e. we're not running dhclient).
Otherwise the ntpd job won't be triggered.

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.

is "ready". This prevents ugly race conditions, e.g. HAL failing to
start because dbus hasn't finished starting yet.
* Support post-start scripts. These are executed after the job's main
process has started but before the job's "started" event is
emitted. For instance, the udev job uses this to perform "udevadm
trigger / settle" to create all devices. Previously this had to be
done in the pre-start script, so the daemon had to started in the
pre-start script as well.

The latter is a security risk, because it allows remote root logins
if a user enables sshd before setting a proper root password.

style of declaring Upstart jobs. While at it, converted them to the
current NixOS module style and improved some option descriptions.
Hopefully I didn't break too much :-)

Purpose: Allow overwriding of properties such as:
config.jobAttrs.sshd.startOn = "never";
thanks to Nicolas Pierron for reviewing and
extending nixpkgs to make this possible
I'll convert most of the jobs ASAP so please don't care
about the depreceateion much right now

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.

* Change the module syntax of the example to follow Eelco's suggestions.
* Add a section "Building your own NixOS CD", which explain how to replace
configuration.nix by the configuration file of a live CD/DVD.

into one argument "modules".
* release.nix: fixed the manual job.
* ISO generation: break an infinite recursion. Don't know why this
suddenly happens. Probably because of the nixpkgs.config change,
but I don't see why. Maybe the option evaluation is too strict.

jobs, e.g. (from the nscd job)
{ name = "nscd";
description = "Name Service Cache Daemon";
startOn = "startup";
stopOn = "shutdown";
environment = { LD_LIBRARY_PATH = nssModulesPath; };
preStart =
''
mkdir -m 0755 -p /var/run/nscd
mkdir -m 0755 -p /var/db/nscd
'';
exec = "${pkgs.glibc}/sbin/nscd -f ${./nscd.conf} -d 2> /dev/null";
};
The Upstart job is generated from this. The main goal is to provide
some abstraction from the Upstart syntax. For instance, this should
make it easier to upgrade to newer versions of Upstart, to switch to
an entirely different process management system (e.g. initng or
launchd), or to test a job independantly from Upstart. (However the
startOn and stopOn attributes are tied to Upstart's event model.)

ove QEMU (and other NixOS instances that use a remote filesystem like
NFS):
* Don't take down the network interfaces during shutdown.
* Don't try to unmount the Nix store. Usually, this doesn't work
because it's still in use, but on remote filesystems like CIFS the
`-f' umount flag actually works.
