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.
Fixes#13927

configFile in make-disk-image clashes with clone-config as the latter does
nothing if it finds a a /etc/nixos/configuration.nix during stage-2.
With these changes, a container can have more then one veth-pair. This allows for example to have LAN and DMZ as bridges on the host and add dedicated containers for proxies, ipv4-firewall and ipv6-firewall. Or to have a bridge for normal WAN, one bridge for administration and one bridge for customer-internal communication. So that web-server containers can be reached from outside per http, from the management via ssh and can talk to their database via the customer network.
The scripts to set up the containers are now rendered several times instead of just one template. The scripts now contain per-container code to configure the extra veth interfaces. The default template without support for extra-veths is still rendered for the imperative containers.
Also a test is there to see if extra veths can be placed into host-bridges or can be reached via routing.
This makes the container a bit more secure, by preventing root
creating device nodes to access the host file system, for
instance. (Reference: systemd-nspawn@.service in systemd.)
This moves nixos-containers into its own package so that it can be
relied upon by other packages/systems. This should make development
using dynamic containers much easier.
We need to use wrapped modprobe, so that it finds the right
modules. Docker needs modprobe to load overlay kernel module
for example.
This fixes an an error starting docker if the booted system's kernel
version is different from the /run/current-system profile's one.
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 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
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.
Without the templating (which is still present for imperative containers), it
will be possible to set individual dependencies. Like depending on the network
only if the hostbridge or hardware interfaces are used.
Ported from #3021
This allows the containers to have their interface in a bridge on the host.
Also this adds IPv6 addresses to the containers both with bridged and unbridged
network.
NixOps has infrequent releases, so it's not the best place for keeping
the list of current AMIs. Putting them in Nixpkgs means that AMI
updates will be delivered as part of the NixOS channels.
We now generate a qcow2 image to prevent hitting Hydra's output size
limit. Also updated /root/user-data -> /etc/ec2-metadata/user-data.

Previously this was done in three derivations (one to build the raw
disk image, one to convert to OVA, one to add a hydra-build-products
file). Now it's done in one step to reduce the amount of copying
to/from S3. In particular, not uploading the raw disk image prevents
us from hitting hydra-queue-runner's size limit of 2 GiB.
Allow usage of list of strings instead of a comma-separated string
for filesystem options. Deprecate the comma-separated string style
with a warning message; convert this to a hard error after 16.09.
15.09 was just released, so this provides a deprecation period during
the 16.03 release.

This is a regression introduced by merging the EBS and S3 images. The
EBS images had a special marker /.ebs to prevent the initrd from using
ephemeral storage for the unionfs, but this marker was missing in the
consolidated image.
The fix is to check the file ami-manifest-path on the metadata server
to see if we're an S3-based instance. This does require networking in
the initrd.
Issue #12613.
The default behavior with an m3.medium instance is to relocate
/nix and /tmp to /disk0 because an assumption is made that any
ephemeral disk is larger than the root volume. Rather than make
that assumption, add a check to see if the disk is larger, and
only then relocate /nix and /tmp.
This addresses https://github.com/NixOS/nixpkgs/issues/12613

I've added an alias for multipath_tools to make sure that we don't break
existing configurations referencing the old name.

When using `--ensure-unique-name`, don't needlessly append `"-0"` if the
container name is already unique.
This is especially helpful with NixOps since when it deploys to a
container it uses `--ensure-unique-name`. This means that the container
name will never match the deployment host due to the `"-0"`. Having the
container name and the host name match isn't exactly a requirement, but
it's nice to have and a small change.
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
Modifies libvirt package to search for configs in /var/lib and changes
libvirtd service to copy the default configs to the new location.
This enables the user to change e.g. the networking configuration with
virsh or virt-manager and keep those settings.
This reverts commit 6353f580f9.
Unfortunately cache=none doesn't work with all filesystem options.
