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’.
It specifies what mingetty will be stopped, if a bad filesystem
triggers an emergency shell.
That should be ttyS0 on headless systems, and in that case,
nixos should stop the ttyS0 mingetty from getting in.
If passno is set, then systemd will instantiate a systemd-fsck unit,
which in turn will instantiate a <device>.device unit
(e.g. "none.device"). Since no such device exists, mounting will
fail. So don't set passno.
proxy_arp (and proxy_ndp for ipv6) can be turned on on a few
interfaces (at least 2).
This is mainly useful for creating pseudo-bridges between a real
interface and a virtual network such as VPN or a virtual machine for
interfaces that don't support real bridging (most wlan interfaces).
As ARP proxying acts slightly above the link-layer, below-ip traffic
isn't bridged, so things like DHCP won't work. The advantage above
using NAT lies in the fact that no IP addresses are shared, so all
hosts are reachable/routeable.
Systemd's systemd-vconsole-setup.service reads locale and console
font/keymap settings from these files. In particular, it sets the
virtual console to UTF-8 mode depending on the LANG setting.
This removed the need for the kbd job.
the device has no filesystem yet. Useful in Charon deployments.
The check for an uninitialised filesystem is kind of shaky now.

were redirecting output to /var/log/upstart/<job>, so it didn't work
properly.
* mountall-ip-up: send the USR1 signal to the mountall process by
looking up its PID, rather than doing "pkill -USR1 mountall". This
prevents a very subtle race condition where USR1 is delivered to a
child process of mountall (such as fsck), if pkill sees the child
just before its execve(). There is actually still a race condition
because mountall installs its USR1 handler *after* daemonising, so
mountall-ip-up could accidentally kill mountall. Should report this
to upstream.

breaks VT switching and causes the X server to go to 100% CPU time.

reiserfs now have separate modules that are conditional on
boot.supportedFilesystems and boot.initrd.supportedFilesystems.
By default, these include the filesystems specified in the fsType
attribute in fileSystems. Ext2/3/4 support is currently
unconditional.
Also unbreak the installer test (http://hydra.nixos.org/build/2272302).

many services depend on other services that bring up network interfaces.
Examples are ipv6 tunneling clients or VPNs.
As there are multiple choices for these network-interface-providing services,
it's not nice to hardcore these deps in every service.
This change sets up a generic config option for this purpose.
providers (gw6c/gogoclient/openvpn) can plug into this to signal they bring up
an important interface.
Daemons that need these interfaces, can then depend on the 'all-interfaces' event,
instead of the individual services.
By default, the event fires when network-interfaces completes.
