Empirical data shows response times of over 10s for even simple config
changes on heavily loaded systems (non-accelerated VMs with lots of
stress on the host). So we choose a really large number, hoping that
we won't be back here for a while.
To set up proper factory defaults in Infix we need to drop the default
/etc/sysrepo datastores, initialized at compile-time by Buildroot when
installing netopeer2. The pre-initialized datastores cannot be set up
with new {factory} data in any other way.
The system factory-config is constructed from two parts: static data and
generated data. The latter is:
- hostname (product name + the three last octets of the base MAC)
- interface defaults (depends on number of ports on the device) that
enable IPv6 link-local on all interfaces, and
- per-device unique SSH hostkey for remote NETCONF access, requires
openssl binary on target. Can maybe use openssh for this (TODO).
The hostkeys are saved in /cfg/factory.d/ to prevent them from being
regenerated on every boot.
The script gen-hostkeys and the update of 10-netconf-server.json are
inspired by the netopeer2 scripts merge_hostkey.sh and merge_config.sh,
which do just about the same thing for regular systems.
We bootstrap sysrepo early with all the required models, netopeer2 as
well as our own, by calling sysrepoctl with initial data for {factory}
and {startup} datastores. A local patch to sysrepo is used to allow it
to look for an /etc/factory-default.json instead of compile-time default
data, the patch allows us to have variable amount of objects in the init
data, e.g. number of interface objects.
A system startup-config is generated, if one is mising, from {running}.
We then drop the initial {running} datastore before starting the daemons
sysrepo-plugind and netopeer2-server so that they, and our plugins, are
ready when we load the system startup-config.
Some sanity checks and debug possibilities:
- Ensure /etc/sysrepo exists before copying factory-config
- Keep factory-default.json for debug

Without --force-bind, the address is removed if another routable
address is added to the interface.
While this is likely something that should be configurable in the
future, we choose this mode as the default so that IPs used for
NETCONF connections are not dropped because other addresses are added.
This allows you to define a single "logical" config that can be
tailored to the specific system based on the available interfaces,
base MAC address etc.
Some critical services must never be stopped, and with the unfortunate
separation of runlevel S and 0 in Finit recently, all affected service
definitions must be updated.

Still ways to go here, eth0 should be in a bridge with a vlan1 interface
on top, which in turn should have this config. But let's start here, it
works! :-)

The idea is to, as a plain Infix default, start up devices with DHCP and
IPv4LL/ZeroConf and IPv6 link-local address. Using mDNS the user can
then and push a NETCONF configuration over SSH.

With the new templating support in Finit, and this patch, we can now
very easily enable a ZeroConf service on, e.g., eth0:

That breaks what other packages may have installed already and is not

Add the ability to set and delete system MotD (Message Of The Day)
using the cli.
This patch augments the standard ietf-system yang schema with
a new infix-system schema which contains a new motd leaf.
The default value is hard coded in two places, confd and the rootfs
file /etc/motd. The intention is to fix this in upcoming patches.
Introduces:
exec> configure> set system motd STRING
exec> configure> delete system motd
When researching the systemd tmpfiles.d implementation I discovered the
effort to standarize on /usr/share/factory as a generic factory defaults
for Linux systems. This patch adds a small example factory.cfg file
that is installed as /usr/share/factory/cfg/startup-config.cfg. The
tmpfiles.d backend will then install it as /cfg/startup-config.cfg if
that file is missing at boot. Confd does the rest to bootstrap our
(by default) empty sysrepo db with this startup-config.

This change adds a hook to the startup datastore, we use the ietf-system
module because the module argument is mandatory. The hook runs when all
changes have been saved to the internal store. Since sysrepo has many
startup files in /etc/sysrepo, we saving a JSON copy of all these files
in /cfg/startup-config.cfg, which is persistent. On system bootstrap
this file is merged into the (empty) running datastore, which is what
the sysrepo maintainers recommend to be independent of any yang model
updates that might occur on image upgrades.

Infix integration of klish and klish-plugin-sysrepo.
Initially we add:
More flexible management of running vs. startup: Instead of always
committing changes both to running and startup, commit only modifies
running. To persist changes to startup, the copy command is
introduced. This lets the user copy from factory/startup/running to
startup/running at any time.
Well-known verbs like abort, leave, end, etc.
This commit adds multi-nameserver support using openresolv (resolvconf)
and dnsmasq. This means that a DHCP client (dhcpcd) or VPN client can
be providers of nameservers to the system. Dnsmasq takes over as the
system resolver, except when the user has set up static configuration.
Static nameserver(s), as well as search and options, are always added
first by openresolv to /etc/resolv.conf.
