Peter Simons 91bead9c18 modules/system/boot/loader/grub/memtest.nix: use 'memtest86plus' instead of 'memtest86'
The 'memtest86' package didn't work on any of my machines. 'memtest86plus', on
the other hand, seems to work just fine. Does anyone know why we keep the
seemingly older version around still?

Eelco Dolstra ac53b25f16 Remove handling of "debug2" and "S|s|single" kernel command line options
The "S|s|single" option is handled by systemd (starting
rescue.target).  And the rescue target basically removes the need for
a special debug shell.  (Also, there is "systemd.crash_shell=1" for
starting a shell if systemd crashes.)

Eelco Dolstra f4a3bdd6af Install {rescue,emergency}.{target,service}
Also, symlink kbrequest.target to rescue.target as suggested by the
systemd.special manpage.  This way, you can start a sulogin rescue
shell by pressing Alt+Up.

Eelco Dolstra 884f58fa8a Include libsystemd-daemon.so.* in the initrd since dmsetup needs it
Strangely, this is only case after updating systemd to 197, I didn't
change lvm2...

Eelco Dolstra 96ba0ca283 For some units, use "systemctl restart" rather than "systemctl stop/start"
During a configuration switch, changed units are stopped in the old
configuration, then started in the new configuration (i.e. after
running the activation script and running "systemctl daemon-reload").
This ensures that services are stopped using the ExecStop/ExecStopPost
commands from the old configuration.

However, for some services it's undesirable to stop them; in
particular dhcpcd, which deconfigures its network interfaces when it
stops.  This is dangerous when doing remote upgrades - usually things
go right (especially because the switch script ignores SIGHUP), but
not always (see 9aa69885f0).  Likewise,
sshd should be kept running for as long as possible to prevent a
lock-out if the switch fails.

So the new option ‘stopIfChanged = false’ causes "systemctl restart"
to be used instead of "systemctl stop" followed by "systemctl start".
This is only proper for services that don't have stop commands.  (And
it might not handle dependencies properly in some cases, but I'm not
sure.)

Mathijs Kwik 16a9bcfe81 add support for systemd mount units
This is mainly useful for specifying mounts that depend on other
units. For example sshfs or davfs need network (and possibly
nameservices).

While systemd makes a distinction between local and remote
filesystems, this only works for in-kernel filesystems such as
nfs and cifs.

fuse-based filesystems (such as sshfs and davs) are classified as
local, so they fail without networking. By explicitly declaring these
mounts as full systemd units (as opposed to having systemd generate
them automatically from /etc/fstab), dependencies can be specified as
on every other unit.

In the future, we can probably port NixOS' filesystems handling to use
these native systemd.mount units and skip /etc/fstab altogether, but
this probably requires additional changes, such as starting systemd
even earlier during boot (stage 1).

I'm not any good at perl, and I only came up with this after many

But until this, memtest was broken, and extraPrepareConfig as well, in grub.

Eelco Dolstra bd7ea9be58 sysinit.target: Drop the dependency on local-fs.target and swap.target
Having all services with DefaultDependencies=yes depend on
local-fs.target is annoying, because some of those services might be
necessary to mount local filesystems.  For instance, Charon's
send-keys feature requires sshd to be running in order to receive LUKS
encryption keys, which in turn requires dhcpcd, and so on.  So we drop
this dependency (and swap.target as well for consistency).  If
services require a specific mount, they should use RequiresMountsFor
in any case.

aszlig a333f7212e systemd: Fail if kernel features are missing.
This has rendered my system unbootable, because I forgot to enable AUTOFS4 in my
custom kernel. In addition to AUTOFS4, this includes (hopefully) all other
kernel features needed by systemd, as listed in the README:

REQUIREMENTS:
  Linux kernel >= 2.6.39
    with devtmpfs
    with cgroups (but it's OK to disable all controllers)
    optional but strongly recommended: autofs4, ipv6

Autofs4 is not a requirement here, but in our case it turns out that the system
is not able to boot properly with a LUKS-enabled system (or at least not on _my_
system).

Eelco Dolstra 1a82024dd8 In the tests, don't start agetty on /dev/ttyS0
Running agetty on ttyS0 interferes with the backdoor, which uses ttyS0
as its standard error.  After agetty starts, writes to the stderr file
descriptor will return EIO (though doing "exec 2>/proc/self/fd/2" will
miracuously fix this).

Eelco Dolstra b4a1893cdd systemd-vconsole-setup: Don't put the X server in non-raw mode
‘systemd-vconsole-setup’ by default operates on /dev/tty0, the
currently active tty.  Since it puts /dev/tty0 in Unicode or ASCII
mode, if the X server is currently active when it runs, keys such as
Alt-F4 won't reach the X server anymore.  So use /dev/tty1 instead.

Eelco Dolstra b606165bd9 Allow a unit to declare "triggers" that force a restart
The triggers are just arbitrary strings that are included in the unit
under X-Restart-Triggers.  The idea is that if they change between
reconfigurations, switch-to-configuration will restart the unit
because its store path changed.  This is mostly useful for services
that implicitly depend on generated files in /etc.  Thus you can say

  restartTriggers = [ confFile ];

where ‘confFile’ is the derivation that generated the /etc file in
question.

Eelco Dolstra d7458b5fc2 Split the monolithic network-interface service into multiple units
For each statically configured interface, we now create a unit
‘<interface>-cfg.service’ which gets started as soon as the network
device comes up.  Similarly, each bridge defined in
‘networking.bridges’ and virtual interface in ‘networking.interfaces’
is created by a service ‘<interface>.service’.

So if we have

  networking.bridges.br0.interfaces = [ "eth0" "eth1" ];
  networking.interfaces =
    [ { name = "br0";
        ipAddress = "192.168.1.1";
      }
    ];

then there will be a unit ‘br0.service’ that depends on
‘sys-subsystem-net-devices-eth0.device’ and
‘sys-subsystem-net-devices-eth1.device’, and a unit ‘br0-cfg.service’
that depends on ‘sys-subsystem-net-devices-br0.device’.

Eelco Dolstra 891be375b5 Make unitConfig/serviceConfig attribute sets
So instead of:

  boot.systemd.services."foo".serviceConfig =

      CPUShare=500
    '';

you can say:

  boot.systemd.services."foo".serviceConfig.StartLimitInterval = 10;
  boot.systemd.services."foo".serviceConfig.CPUShare = 500;

This way all unit options are available and users can set/override
options in configuration.nix.
