Eelco Dolstra b15e1fbb08 Boot loader refactoring
- Renamed system.build.menuBuilder to system.build.installBootLoader.

- ‘install-grub.pl’ (formerly grub-menu-builder.pl) now generates the
  GRUB menu *and* installs GRUB (if necessary).

- ‘switch-to-configuration.sh’ has no boot loader specific knowledge
  anymore.  It just calls installBootLoader.

Eelco Dolstra f07f221f0e Replace grub-menu-builder with a much faster version
The old GRUB menu builder script is quite slow, typically taking
several seconds.  This is a real annoyance since it's run every time
you switch to a new configuration.  Therefore this patch replaces the
Bash script with a much faster Perl script.  In a VirtualBox test, the
execution time went from 2.7s to 0.1s.  The Perl version is also more
correct because it uses XML to get the GRUB configuration (through
builtins.toXML), so there are no shell escaping issues.

The new script currently lacks support for subconfigurations defined
through "nesting.children".

Eelco Dolstra 86d8d62d16 * Allow Upstart jobs to declare that they shouldn't be restarted by
switch-to-configuration.  E.g. the X server shouldn't be restarted
  because that kills all the X clients.

Eelco Dolstra 3495a773f9 * Improved Upstart job handling in switch-to-configuration. It no
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.

Peter Simons 20b364f4de Reverting revisions 30103-30106: "always set nixpkgs.config.{state,store}Dir", etc.
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.

Eelco Dolstra 7579933824 * Don't mount /dev/cgroup with the "ns" subsystem. If it's mounted,
then every unshare(CLONE_NEWNS) system call causes a new entry to be
  created in /dev/cgroup/<pid>, which is not removed automatically.
  This can cause subsequent calls to unshare() to fail if the PID has
  wrapped around.  Worse, a large number of entries in /dev/cgroup
  causes a very substantial system slowdown: doing 10,000
  fork()/unshare(CLONE_NEWNS)/exit() calls took 21s without the "ns"
  subsystem, but 2m43s with it, and the system slows down permanently
  until the entries in /dev/cgroup are removed (going to a load of > 6
  on my laptop).

  This is particularly important for Nix because its chroot feature
  uses unshare(CLONE_NEWNS).  (http://yellowgrass.org/issue/Nix/219)

Eelco Dolstra c4f910f550 * Substitute the path of the system derivation directly in the stage 2
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.

Eelco Dolstra f729f12e4e Some cleanups in the activation script:
* 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).

Eelco Dolstra c1295661c4 * Added a command `nixos-rebuild build-vm-with-bootloader'. This is

  1 or 2) rather than booting directly from the kernel/initrd.  Thus
  it allows testing of GRUB.
