caching. This makes a huge performance difference (e.g. from 4 MB/s
`dd' throughput to 140 MB/s on the Hydra machines). As the QEMU
manual says: "Some block drivers perform badly with
‘cache=writethrough’, most notably, qcow2."

Adding an assert to upstart jobs, so those with preStop will always need an exec or
script, otherwise the preStop will not be run.

shutdown. (Portmap and statd are needed during shutdown to unmount
NFS volumes but have open files in /var/run.)
* In the shutdown job, don't kill PIDs belonging to Upstart jobs that
are still running. If they don't stop on the "starting shutdown"
event, then they're needed during shutdown (such as portmap and
statd).
* NFS test: test whether the shutdown quickly unmounts NFS volumes
(i.e. whether portmap and statd are still running).

sm-notify; for the client: statd / sm-notify before mountall). This
is important to allow locking to work correctly.

When starting multiple VMs, some will have perfectly synchronised
clocks, while others will have their clocks run much slower (say, a
factor of 5).

a daemon (it just starts some kernel threads). In the post-stop
script, stop the kernel threads.
* exportfs: fix the createMountPoints option.
* Mount the nfsd filesystem on /proc/fs/nfsd because mountd prefers
this.

swapfiles cannot be unmounted or even remounted read-only.
* In the remount, pass `-t none' to get a more informative error
message if the filesystem is in use.

it allows the `mountall' task to start mounting filesystems as soon
as udev is running and devices become available (i.e. it doesn't
have to wait for all devices). This means that some jobs should
depend on "stopped udevtrigger" instead of "started udev".

during boot. Mountall ensures that these are done in the right
order. It's informed by udev about devices becoming available. It
emits some Upstart events upon reaching certain states, in
particular ‘local-filesystems’ after all local filesystems have been
mounted successfully, ‘remote-filesystems’ after all network
filesystems have been mounted, and ‘filesystem’ (sic) when all
filesystems have been mounted.
Currently, if a filesystem fails to mount or doesn't exist, then the
mingettys won't start and the boot will appear to hang. This is
because mountall doesn't emit an event for failing filesystems and
waits indefinitely for the filesystems to become available.
* The ‘filesystems’ and ‘swap’ Upstart jobs are gone. (Support for
encrypted swap devices is temporarily gone.)
* Generate a proper /etc/fstab from the ‘fileSystems’ and
‘swapDevices’ options.

`su'.
* The `usermod' from `shadow' allows setting a supplementary group
equal to the user's primary group, so the special hack for the
`nixbld' group is no longer needed.
* Removed /etc/default/passwd since it's not used by the new passwd.
The hash is configured in pam_unix.
* Move some values for `security.setuidPrograms' and
`security.pam.services' to the appropriate modules.

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).
