If a kernel without CONFIG_UEVENT_HELPER set is used with NixOS, the file
/proc/sys/kernel/hotplug does not exist. Before writing to it to disable
this deprecated mechanism, we have to ensure it actually exists because
otherwise the activation script will fail.
This updates rdnssd to the following:
* Using the systemd interfaces directly
* Using the rdnssd user instead of the root user
* Integrating with resolvconf instead of writing directly to /etc/resolv.conf
The i686-linux test has never worked and I wrote the VM test only on
x86_64-linux to verify whether hardening mode works. I don't know why it
fails on i686-linux, but that might be because the inner VirtualBox VM
we're starting during the VM test doesn't use hardware virtualization.
Closes#5708.

Sometimes, keys aren't properly recognized the first time, so in order
to make sure they get through, always resend the key again on retry.
In this case the worst that could happen is that the VM is started over
and over again, but never in parallel, so that's fine because we're
checking for successful startup 10 seconds after the keypress.

It's not nice to send the escape key over and over again just to ensure
the popup is closed, because even *if* it fails to close the popup 4
times in a row it's just very unlikely that it will be closed. But in
order to make really sure, we might need to do a screenshot and detect
visual changes.

This is essentially what's been done for the official NixOS build slaves
and I'm using it as well for a few of my machines and my own Hydra
slaves.
Here's the same implementation from the Delft server configurations:

Many bus clients get hopelessly confused when dbus-daemon is
restarted. So let's not do that.
Of course, this is not ideal either, because we end up stuck with a
possibly outdated dbus-daemon. But that issue will become irrelevant
in the glorious kdbus-based future.
Hopefully this also gets rid of systemd getting stuck after
dbus-daemon is restarted:

It has been removed by 71a197bc6e.
I'm reintroducing the test mainly because it actually *is* useful,
because right now, machines with mdraid will not boot. In order to
prevent such things from happening in the future, we should *not* remove
this VM test again.
If it really goes back to failing randomly, we should really try to fix
it instead of removing it again.
Of course it fails right now because of the mdraid bump in 7719f7f.
Also, if you want to have additional info about the reasons, have a look
at the commit message of 666cf992f0.

I'm increasing it to 100MB to make sure, any bootloader will fit with
all its stages. Of course, right now the reason why GRUB doesn't fit
into the partition is because of mdadm 3.3.2 and thus the initrd taking
all the space, but in order to avoid confusion on why the *boot* loader
fails in the VM tests, I've increased the size.

There are a number of hidden restrictions on the syslinux
configuration file that come into play when UNetbootin
compatiblity is desired. With this commit these are documented.
This changes the bootloader for iso generation from Grub to
syslinux. In addition this adds USB booting support, so that
"dd" can be used to burn the generated ISO to USB thumbdrives
instead of needing applications like UnetBootin.
The group is specified using a singleton list, so the loaOf merging is
done by iterating through the list items with imap, so it enumerates
every element and sets that as the default "name" attribute.
From lib/types:143:
name = elem.name or "unnamed-${toString defIdx}.${toString elemIdx}";
So, people get groups like "unnamed-X.Y" instead of "mpd".

It now strictly evaluates all remaining attributes, preventing
unevaluated thunks that cannot be garbage-collected. It's also applied
to all jobs in Nixpkgs' release.nix.
This reduces hydra-eval-jobs' memory consumption on the 14.12
release-combined jobset from 5.1 GB to 2.0 GB.
Fixes the useless collisions in the system path.
The 64bit and 32bit variants have the same files, hence
it's pointless to put the 32bit pulseaudio in systemPackages.
Rather than using openssl to hash the password at build time, and hence
leaving the plaintext password world-readable in the nix store, we can
instead hash the password in the nix expression itself using
builtins.hashString.
This patch resolves all uid/gid conflicts except for nobody/nogroup (seems
to make sense that these are the same).
All conflicts where determined mechanically, but resolutions were manual.
This patch also marks uids/gids with no corresponding group/user as "unused"
(aka. reserved).
Briefly,
- tss group conflicts with dhcpcd
The tss group id conflicts with dhcpcd: assign
a new number and add a corresponding tss user.
- elasticsearch uid conflicts with haproxy gid
- resolve firebird/munin conflict
- fix fourstorehttp{,d} typo
- fix ghostOne typo: the service module refers to gids.ghostone, so use that
in ids
- memcached uid conflicts with users gid
- nagios uid conflicts with disks gid
- nscd uid conflicts with wheel gid
- ntp uid conflicts with tty gid
- resolve postfix/postdrop id uid
- redis uid conflicts with keys gid
- sshd uid conflicts with kmem gid
- tcryptd uid conflicts with openldap gid
- unifi uid conflicts with docker gid
- uptimed uid conflicts with utmp gid
- zope2 uid conflicts with connman gid
- tomcat uid/gid mismatch
With the new evaluation of arguments, pkgs is now defined by the
configuration, which implies that option declaration with pkgs.lib
will cause an infinite loop.
Ideally the module system could be configured pretty much completely by
the contents of the modules themselves, so add comments about avoiding
complicating it further and possibly removing now-redundant
configurability from the existing interface.
This allows for module arguments to be handled modularly, in particular
allowing the nixpkgs module to handle the nixpkgs import internally.
This creates the __internal option namespace, which should only be added
to by the module system itself.

By making askPassword an option, desktop environment modules can
override the default x11_ssh_askpassword with their own equivalent for
better integration. For example, KDE 5 uses plasma5.ksshaskpass instead.
Major changes
- Port to systemd timers: for each archive configuration is created a
tarsnap@archive-name.timer which triggers the instanced service unit
- Rename the `config` option to `archives`
Minor/superficial improvements
- Restrict tarsnap service capabilities
- Use dirOf builtin
- Set executable bit for owner of tarsnap cache directory
- Set IOSchedulingClass to idle
- Humanize numbers when printing stats
- Rewrite most option descriptions
- Simplify assertion
Since we restart all active target units (of which there are many),
it's hard to see the units that actually matter. So don't print that
we're starting target units that are already active.
‘nixos-rebuild dry-activate’ builds the new configuration and then
prints what systemd services would be stopped, restarted etc. if the
configuration were actually activated. This could be extended later to
show other activation actions (like uids being deleted).
To prevent confusion, ‘nixos-rebuild dry-run’ has been renamed to
‘nixos-rebuild dry-build’.
Currently just makes sure that by default it's possible to open a
terminal.
And exactly this should be the main point that might confuse users of i3
in NixOS, because i3 doesn't print a warning/error if it is unable to
start the terminal emulator.
Thanks to @waaaaargh for reporting this issue.

The grsec-lock unit fails unless /proc/sys/kernel/grsecurity/grsec_lock
exists and so prevents switching into a new configuration after enabling
grsecurity.sysctl.
If the host is shutting down, machinectl may fail because it's
bus-activated and D-Bus will be shutting down. So just send a signal
to the leader process directly.
Fixes#6212.
This was lost back in
ffedee6ed5. Getting this to work is
slightly tricky because ssh-agent runs as a user unit, and so doesn't
know the user's $DISPLAY.

HAProxy fails to start with the default 'config'. Better disable it and
assert that the user provides a suitable 'config'. (AFAICS, there cannot
really be a default config file for HAProxy.)
The networkd implementation sets systemd.services.dhcpcd.enable to
false in nixos/modules/tasks/network-interfaces-systemd.nix. So we need
to respect that in the dhcpcd module.
If we don't, the resumeCommand is set nevertheless, which causes the
post-resume.service to fail after resuming:
Failed to reload dhcpcd.service: Unit dhcpcd.service is masked.
post-resume.service: main process exited, code=exited, status=1/FAILURE
Failed to start Post-Resume Actions.
Dependency failed for Post-Resume Actions.
Unit post-resume.service entered failed state.

Since Chromium version 42, we have a new user namespaces sandbox in the
upstream project. It's more integrated so the chrome://sandbox page
reports it as "Namespace Sandbox" instead of SUID sandbox, which we were
re-using (or abusing?) in our patch.
So if either "SUID Sandbox" or "Namespace Sandbox" reports with "Yes",
it's fine on our side.
