Lluís Batlle i Rossell 33ed225a84 Making the /dev and /dev/shm tmpfs sizes configurable.
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.

Eelco Dolstra 0432766399 * Fall back to the kernel modules used at boot time if the modules in
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.

Lluís Batlle i Rossell 13ee735395 Making nixos work well with the new names 'linuxPackages' in stdenv-updates, additionally
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.

Marc Weber fdc63c54e4 enhance phpIni documentation
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 (?)

Eelco Dolstra c9e4b46d48 * Ugly hack: for CIFS mounts, retry the mount a few times (just as in
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# [   23.271708]  CIFS VFS: No response for cmd 114 mid 1
  server# [   23.272443]  CIFS VFS: cifs_mount failed w/return code = -112
  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...

Eelco Dolstra 170331be30 * Don't use /hostfs to signal the test driver that a VM is up, but
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.

Eelco Dolstra 6c9059e717 * Added an option `boot.initrd.availableKernelModules' that specifies
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.

Eelco Dolstra 82c3e2aa50 * Updated poweroff/reboot/maintenance mode for Upstart 0.6. Upstart
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.
