properly.
* mountall-ip-up: send the USR1 signal to the mountall process by
looking up its PID, rather than doing "pkill -USR1 mountall". This
prevents a very subtle race condition where USR1 is delivered to a
child process of mountall (such as fsck), if pkill sees the child
just before its execve(). There is actually still a race condition
because mountall installs its USR1 handler *after* daemonising, so
mountall-ip-up could accidentally kill mountall. Should report this
to upstream.

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.

This allows setting a fixed device name per array, thus ensuring that at boot,
the arrays will always be mounted with the same names. I think this allows
solving the problem of grub getting confused about softraid device names
(prefix and root), if the devices always get the same naming at initrd.

I set it as default because users can benefit of this without having to prepare
their nixos first, and I don't think it will break any nixos for the initrd

reiserfs now have separate modules that are conditional on

By default, these include the filesystems specified in the fsType

popt-0.16 and cryptsetup-1.4.1 both generated pkgconfig (in contrast
to older versions). The pkgconfig files (popt.pc and cryptsetup.pc)
contain references into the store that are not removed by patchelf and
stage-1 fails with errors like: "output is not allowed to refer to
path `/nix/store/qccjhn063cfv171rcaxvxh0yk96zf7l2-cryptsetup-1.4.1'".
Now, only the cryptsetup binaries and its dependencies are copied,
determined by ldd. In addition the cryptsetup binary and lvm are
tested after patchelf has adjusted the library paths.
Thanks to Peter Simons and Eelco Dolstra for giving the rights hints.

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.

is a directory. Not handling this correctly led to /etc/static

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)

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.
