treewide: fix fallout of ip-up deprecation
See #18319 for details. Starting network-online.target manually does not
work as it hangs indefinitely.

Additionally, don't treat avahi and dhcpcd special and sync their systemd units
with the respective upstream suggestion.

Alexander Ried 27bc34f1e4 treewide: deprecate ip-up.target (#18319)
Systemd upstream provides targets for networking. This also includes a target network-online.target.

In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.

nixos/stage2: Fix mounting special filesystems
This partially reverts commit ab9537ca22.

From the manpage of systemd-nspawn(1):

  Note that systemd-nspawn will mount file systems private to the
  container to /dev, /run and similar.

Testing this in a shell turns out:

$ sudo systemd-nspawn --bind-ro=/nix/store "$(readlink "$(which ls)")" /proc
Spawning container aszlig on /home/aszlig.
Press ^] three times within 1s to kill container.
/etc/localtime does not point into /usr/share/zoneinfo/, not updating
container timezone.

Container aszlig exited successfully.

So the test on whether PID 1 exists in /proc is enough, because if we
use PID namespaces there actually _is_ a PID 1 (as shown above) and the
special file systems are already mounted. A test on the $containers
variable actually mounts them twice.

This unbreaks NixOS containers and I've tested this against the
containers-imperative NixOS test.

Domen Kožar a6670c1a0b Fixes #18124: atomically replace /var/setuid-wrappers/ (#18186)
Before this commit updating /var/setuid-wrappers/ folder introduced
a small window where NixOS activation scripts could be terminated
and resulted into empty /var/setuid-wrappers/ folder.

That's very unfortunate because one might lose sudo binary.

Instead we use two atomic operations mv and ln (as described in
https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/)
to achieve atomicity.

Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints
were removed in installation scripts and in boot process.

Tested:

- upgrade /var/setuid-wrappers/ from folder to a symlink
- make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted

Profpatsch 488f0d9cb3 systemd-unit-options: startAt can be a list
OnCalendar entrys can be specified multiple times in a systemd timer, to
make more complex scheduling possible.

Tested by manually checking the timer generated by the following:

    systemd = {
      services.huhu = {
        description = "meh";
        wantedBy = [ "default.target" ];
        serviceConfig.ExecStart = "/bin/sh -c 'printf HUHU!'";
        startAt = [ "*:*:0/30" "*:0/1:15" ];
      };
    };

It prints HUHU to the log at seconds 0, 15 and 30 of each minute.

Nikolay Amiantov 6efcfe03ae nixos filesystems: unify early filesystems handling
A new internal config option `fileSystems.<name>.early` is added to indicate
that the filesystem needs to be loaded very early (i.e. in initrd). They are
transformed to a shell script in `system.build.earlyMountScript` with calls to
an undefined `specialMount` function, which is expected to be caller-specific.
This option is used by stage-1, stage-2 and activation script to set up and
remount those filesystems.  Options for them are updated according to systemd
defaults.

obadz 3d16af70bf nixos/stage-1: add mechanism which lustrates all impurities from / (#17784)
lustrate /ˈlʌstreɪt/ verb.
  purify by expiatory sacrifice, ceremonial washing, or some other
  ritual action.

- sudo touch /etc/NIXOS_LUSTRATE
  ⇒ on next reboot, during stage 1, everything but /nix and /boot
  is moved to /old-root
- echo "etc/passwd" | sudo tee -a /etc/NIXOS_LUSTRATE
  ⇒ on next reboot, during stage 1, everything but /nix and /boot
  is moved to /old-root; except /etc/passwd is copied back.

Useful for installing NixOS in place on another distro. For instance:

$ nix-env -iE '_: with import <nixpkgs/nixos> { configuration = {}; }; with config.system.build; [ nixos-generate-config manual.manpages ]'
$ sudo mkdir /etc/nixos
$ sudo `which nixos-generate-config`

… edit the configuration files in /etc/nixos using man configuration.nix
  if needed

  maybe add: users.extraUsers.root.initialHashedPassword = "" ?

… Build the entire NixOS system and link it to the system profile:
$ nix-env -p /nix/var/nix/profiles/system -f '<nixpkgs/nixos>' -A system --set

… If you were using a single user install:
$ sudo chown -R 0.0 /nix

… NixOS is about to take over
$ sudo touch /etc/NIXOS
$ sudo touch /etc/NIXOS_LUSTRATE

… Let's keep the configuration files we just created
$ echo etc/nixos | sudo tee -a /etc/NIXOS_LUSTRATE

$ sudo mv -v /boot /boot.bak &&
  sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot
$ sudo reboot

… NixOS boots, Stage 1 moves all the old distro stuff in /old-root.

Thomas Tuegel 68922e3f74 nixos/stage-1: use readlink -e in builder
The builder has this convoluted `while` loop which just replicates
`readlink -e`. I'm sure there was a reason at one point, because the
loop has been there since time immemorial. It kept getting copied
around, I suspect because nobody bothered to understand what it actually
did.

Incidentally, this fixes #17513, but I have no idea why.

etc: remove obsolete directories
This patch adds handling of a directory becoming a symlink in
/etc. Before this patch, the directory wasn't removed and then
symlinking failed, which caused directory not being updated at all.

The idea for the patch goes to @abbradar at
https://github.com/NixOS/nixpkgs/issues/16978#issuecomment-232921903:
> A heuristic idea for this -- a function `isStatic :: Path -> Bool`:
>
> * if path `/etc/foo` is a file, return True iff it's a symlink to `/etc/static/foo`.
> * if path is a directory, return True iff for all items in it `isStatic` is True.
>
> On any conflicts, if old path is static, it's safe to replace and/or
> delete stale. Otherwise make a backup and notify the user via a
> journal entry and console output.

The only difference here -- it will not replace user configs.

This also fixes https://github.com/NixOS/nixpkgs/issues/16978.

A disabled systemd service with a "startAt" attribute, like this:

  systemd.services.foo-service = {
    enable = false;
    startAt = "*-*-* 05:15:00";
    ...
  };

will cause the following errors in the system journal:

  systemd[1]: foo-service.timer: Refusing to start, unit to trigger not loaded.
  systemd[1]: Failed to start foo-service.timer.

Fix it by not generating the corresponding timer unit when the service
is disabled.

Bjørn Forsman aeb516c741 nixos/grub: change state file device separator from ':' to ','
':' is currently used as separator in /boot/grub/state for the list of
devices GRUB should be installed to. The problem is that ':' itself may
appear in a device path:

  /dev/disk/by-id/usb-SanDisk_Cruzer_20043512300546C0B317-0:0

With such a path, NixOS will install GRUB *every* time, because it
thinks the configuration differs from the state file (due to the wrong
list split). Fix it by using ',' as separator.

For existing systems with GRUB installed on multiple devices, this
change means that GRUB will be installed one extra time.

NixOS is even more of a server OS than Debian, and I can think of no
reason to make users jump through this sort of hoop.

Eelco Dolstra 845c9b50bf boot.initrd.luks.devices: Change into an attribute set
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.

nixos/stage-1: Don't kill kernel threads
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.

   and if a "default" attribute is defined.

 - Enforce that the value of the "example" attribute is wrapped with "literalExample"
