Since systemd version 230, it is required to have a machine-id file
prior to the startup of the container. If the file is empty, a transient
machine ID is generated by systemd-nspawn.
See systemd/systemd#3014 for more details on the matter.
This unbreaks all of the containers-* NixOS tests.

Closes: #15808
The primary motivation here is to get rid of builderDefs, but now the
resulting font directory is also linked into /run/current-system/sw,
which fixes#15194.
VBoxService needs dbus in order to work properly, which failed to start
up so far, because it was searching in /run/current-system/sw for its
configuration files.
We now no longer run with the --system flag but specify the
configuration file directly instead.
This fixes at least the "simple-gui" test and probably the others as
well, which I haven't tested yet.

We can't use waitForWindow here because it runs xwininfo as user root,
who in turn is not authorized to connect to the X server running as
alice.
So instead, we use xprop from user alice which should fix waiting for
the VirtualBox manager window.

The existence of $root/var/lib/private/host-notify as a socket
prevented a bind mount:
container foo[8083]: Failed to create mount point /var/lib/containers/foo/var/lib/private/host-notify: No such device or address
The VirtualBox tests so far ran the X server as root instead of user
"alice" and it did work, because we had access control turned off by
default.
Fortunately, it was changed in 1541fa351b.
As a side effect, it caused all the VirtualBox tests to fail because
they now can't connect to the X server, which is a good thing because
it's a bug of the VirtualBox tests.
So to fix it, let's just start the X server as user alice.

Regression introduced by d84741a4bf.
The mentioned commit actually is a good thing, because we now get the
output from the X session.
Unfortunately, for the i3wm test, the i3-config-wizard prints out the
raw keyboard symbols directly coming from xcb, so the output isn't
necessarily proper UTF-8.
As the XML::Writer already expects valid UTF-8 input, we assume that
everything that comes into sanitise() will be UTF-8 from the start. So
we just decode() it using FB_DEFAULT as the check argument so that
every invalid character is replaced by the unicode replacement
character:
https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character
We simply re-oncode it again afterwards and return it, so we should
always get out valid UTF-8 in the log XML.

This allows setting options for the same LUKS device in different
modules. For example, the auto-generated hardware-configuration.nix
can contain
boot.initrd.luks.devices.crypted.device = "/dev/disk/...";
while configuration.nix can add
boot.initrd.luks.devices.crypted.allowDiscards = true;
Also updated the examples/docs to use /disk/disk/by-uuid instead of
/dev/sda, since we shouldn't promote the use of the latter.
... rather than ~/.xsession-errors. It might make sense to make this
the default, in order to eliminate ad hoc, uncentralised, poorly
discoverable log files.
This ensures that "journalctl -u display-manager" does what you would
expect in 2016. However, the main reason is to ensure that our VM
tests show the output of the X server.
A slight problem is that with KDE user switching, messages from the
various X servers end up in the same place. However, that's an
improvement over the previous situation, where the second X server
would overwrite the /var/log/X.0.log of the first. (This was caused by
the fact that we were passing a hard-coded value for -logfile.)
For now, leave the old implementation under `man-old` attribute.
Small warning: I had a leftover ~/.nix-profile/man from an old package,
which caused man-db's man prefer it and ignore ~/.nix-profile/share/man.
The PATH->MANPATH code just selects the first match for each PATH item.
The motivation is using sudo in chroot nix builds, a somewhat
special edge case I have and pulling system path into chroot
yields to some very nasty bug like

This reverts commit c25907d072.
I think this commit broke the NixOS service for NetworkManager. At least
with this, and the two previous reverts, everything is back to normal.
(With multiple-outputs split, it would have reduced the closure size by
3 MiB.)
This reverts commit 7ac1ef05fa.
One of a few reverts needed to unbreak networkmanager NixOS service
since the multiple-output split (to save 3 MiB of closure size).
This reverts commit 2875293615.

Move Subsonic state directory from `/var/subsonic` to
`/var/lib/subsonic`, since the general convention is for each
application to put its state directory there.
Also, automatically set the home directory of the `subsonic` user to the
value of `config.services.subsonic.home`, rather than setting it to a
value hardcoded in the module. This keeps the home directory of the
`subsonic` user and the state directory for the Subsonic application in
sync.
leveraging users.users.<user>.createHome instead of a preStart script.
preStart script is still required to ensure proper creation of logging
directory.
This properly implements revert in

We used to have which='type -P' alias, but really it's best to just
rely on which package, only 88K in size.

The chroot caps restriction disallows chroot'ed processes from running
any command that requires `CAP_SYS_ADMIN`, breaking `nixos-rebuild`. See
e.g., https://github.com/NixOS/nixpkgs/issues/15293
This significantly weakens chroot protections, but to break
nixos-rebuild out of the box is too severe.
The list of public proxies is updated now and again and it's probably a
good idea to always work from the most recent list, rather than the one
that is shipped with the release. This can be crucial in case of
resolvers that are revealed to have gone rogue or otherwise have been
compromised.
As @edolstra pointed out that the kernel module might be painful to
maintain. I strongly disagree because it's only a small module and it's
good to have such a canary in the tests no matter how the bootup process
looks like, so I'm going the masochistic route and try to maintain it.
If it *really* becomes too much maintenance burden, we can still drop or
disable kcanary.

We don't want to push out a channel update whenever this test fails,
because that might have unexpected and confused side effects and it
*really* means that stage 1 of our boot up is broken.

We already have a small regression test for #15226 within the swraid
installer test. Unfortunately, we only check there whether the md
kthread got signalled but not whether other rampaging processes are
still alive that *should* have been killed.
So in order to do this we provide multiple canary processes which are
checked after the system has booted up:
* canary1: It's a simple forking daemon which just sleeps until it's
going to be killed. Of course we expect this process to not
be alive anymore after boot up.
* canary2: Similar to canary1, but tries to mimick a kthread to make
sure that it's going to be properly killed at the end of
stage 1.
* canary3: Like canary2, but this time using a @ in front of its
command name to actually prevent it from being killed.
* kcanary: This one is a real kthread and it runs until killed, which
shouldn't be the case.
Tested with and without 67223ee and everything works as expected, at
least on my machine.

This is a regression test for #15226, so that the test will fail once we
accidentally kill one or more of the md kthreads (aka: if safe mode is
enabled).

Unfortunately, pkill doesn't distinguish between kernel and user space
processes, so we need to make sure we don't accidentally kill kernel
threads.
Normally, a kernel thread ignores all signals, but there are a few that
do. A quick grep on the kernel source tree (as of kernel 4.6.0) shows
the following source files which use allow_signal():
drivers/isdn/mISDN/l1oip_core.c
drivers/md/md.c
drivers/misc/mic/cosm/cosm_scif_server.c
drivers/misc/mic/cosm_client/cosm_scif_client.c
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c
drivers/staging/rtl8188eu/core/rtw_cmd.c
drivers/staging/rtl8712/rtl8712_cmd.c
drivers/target/iscsi/iscsi_target.c
drivers/target/iscsi/iscsi_target_login.c
drivers/target/iscsi/iscsi_target_nego.c
drivers/usb/atm/usbatm.c
drivers/usb/gadget/function/f_mass_storage.c
fs/jffs2/background.c
fs/lockd/clntlock.c
fs/lockd/svc.c
fs/nfs/nfs4state.c
fs/nfsd/nfssvc.c
While not all of these are necessarily kthreads and some functionality
may still be unimpeded, it's still quite harmful and can cause
unexpected side-effects, especially because some of these kthreads are
storage-related (which we obviously don't want to kill during bootup).
During discussion at #15226, @dezgeg suggested the following
implementation:
for pid in $(pgrep -v -f '@'); do
if [ "$(cat /proc/$pid/cmdline)" != "" ]; then
kill -9 "$pid"
fi
done
This has a few downsides:
* User space processes which use an empty string in their command line
won't be killed.
* It results in errors during bootup because some shell-related
processes are already terminated (maybe it's pgrep itself, haven't
checked).
* The @ is searched within the full command line, not just at the
beginning of the string. Of course, we already had this until now, so
it's not a problem of his implementation.
I posted an alternative implementation which doesn't suffer from the
first point, but even that one wasn't sufficient:
for pid in $(pgrep -v -f '^@'); do
readlink "/proc/$pid/exe" &> /dev/null || continue
echo "$pid"
done | xargs kill -9
This one spawns a subshell, which would be included in the processes to
kill and actually kills itself during the process.
So what we have now is even checking whether the shell process itself is
in the list to kill and avoids killing it just to be sure.
Also, we don't spawn a subshell anymore and use /proc/$pid/exe to
distinguish between user space and kernel processes like in the comments
of the following StackOverflow answer:
http://stackoverflow.com/a/12231039
We don't need to take care of terminating processes, because what we
actually want IS to terminate the processes.
The only point where this (and any previous) approach falls short if we
have processes that act like fork bombs, because they might spawn
additional processes between the pgrep and the killing. We can only
address this with process/control groups and this still won't save us
because the root user can escape from that as well.
