# Default Service Configuration
## Pseudo Services
The default configuration contains a number of "pseudo services" in the boot
target that don't actually do anything but are merely used as anchors in
service dependencies, i.e. they indicate that some sort of milestone in the
boot sequence has been reached. Everything that is part of that milestone
specifies that it should be run *before* that pseudo service and everything
that requires that this milestone has been reached, specifies that it wants
to run afterwards.
The pseudo targets are (in the order that they are executed):
* vfs
All services that do mount point setup go before this, all service that
depend on the fully mounted rootfs go after this.
* sysinit
The system has reached a sane state, i.e. the hostname is set, the system
clock has a sane value, modules and kernel parameters are loaded, some
very basic, fundamental services are running.
Everything that is part of that setup process goes between `vfs` and
`sysinit`, everything that requires a sane setup goes *after* `sysinit`.
* network
Network configuration is done. All services that do network configuration
should position themselves between `sysinit` and `network`. Everything that
requires a fully configured networking setup should go *after* `network`.
## Default Bootup Services
This section outlines the services for the boot target that are enabled by
default.
The following services are enabled by default and run *before* the `vfs` target
for filesystem setup:
* procfs - mount `procfs` to `/proc` and try to mount additional pseudo
filesystems in `/proc` such as `binfmt_misc`
* tmpfs - mount a `tmpfs` to `/tmp`
* sysfs - mount `sysfs` to `/sys` and try to mount additional pseudo
filesystems in `/sys` (e.g. `securityfs`, `configfs`, ...)
* devfs - mount `devtmpfs` to `/dev`, try to mount additional pseudo
filesystems in `/dev` (e.g. `devpts`, `mqueue`, ...) and try to create
some additional device nodes and symlinks.
* tmpfsvar - mount a `tmpfs` to `/var` and populate it with a default set
of files and directories. Overlay mount `/var/lib` with lower dir on
`/cfg/preserve/var_lib/` and upper on `/cfg/overlay/var_lib/`.
* tmpfsrun - mount a `tmpfs` to `/run`, symlink `/var/run` to `/run` and
`/var/lock` to `/run/lock`.
* mountusr - overlay mount setup for `/usr`. Lower dir is on
`/cfg/preserve/usr/` and upper on `/cfg/overlay/usr/`.
The following services are enabled by default and configured to run *after*
the `vfs` target and *before* the `sysinit` target:
* hostname - reload hostname `/etc/hostname`
* loopback - bring the loopback device up
* modules - iterate over the file `/etc/modules` and try to load each module
using modprobe.
* sysctl - restore kernel parameters using `sysctl --system`. See `sysctl(8)`
for a list of possible locations that the parameters are read from.
* usyslogd - Starts and supervises the `usyslogd` syslog implementation.
* klogd - Starts and supervises the `klogd` daemon.
The following services are enabled by default and configured to run *after*
the `sysinit` target and *before* the `network` target:
* ifcfg - static network configuration
Does the static network configuration outlined in [network.md](network.md)
The following services are enabled by default and configured to run *after*
the `network` target:
* gcrond
## Default Shutdown and Reboot Services
For the shutdown and reboot targets, the following services are executed:
* sigterm - send the SIGTERM signal to all processes and wait for 5 seconds
* sigkill - send the SIGKILL signal to all remaining processes
* ifdown - bring all network interfaces down
* sync - run the sync command
## Additional Services not Enabled by Default
* agetty - A parameterizeable, respawn type `agetty` service. The first
parameter is the terminal device that the getty should run on.
* consolefont - If enabled, run once before sysinit. Sets the console font
to the first parameter.
* dhcpcdmaster - If one or more network interfaces should be configured using
dhcpcd, this service starts a central `dhcpcd` master instance.
* dhcpcd - A parameterizeable single shot service that signals the `dhcpcd`
master that it should configure a specific interface. The first parameter
is the interface that should be configured by `dhcpcd`.
* dnsmasq - A respawn type service for the `dnsmasq` DNS and DHCP server.
* hostapd - If the system should operate a WIFI access point, this respawn
type service can be enabled to manage an instace of the `hostapd` program.
* unbound - A respawn type service that manages an instance of the `unbound`
name resolver.
* hwclock - If the system has a hardware clock, this service can restore the
kernels clock from the hardware at bootup, between the `vfs` and `sysinit`
targets.
* nft - If enabled, restores net filter table rules during boot.
* swclock - For systems that don't have a hardware clock, this service
restores a somewhat usable time from a file during boot.
* swclocksave - For systems that don't have a hardware clock, this service
saves the current time to a file during shutdown or reboot.
* sshd_keygen - A wait type service that generates host keys for the OpenSSH
server and then disables itself.
* sshd - Starts an OpenSSH server after the network pseudo service and after
the sshd_keygen service.
* nginx - Starts the Nginx server after the network pseudo serivce.

# Static Network Configuration
The default configuration provides multiple services that perform network
initialization and static configuration using helper scripts that require
programs from the `iproute2` package.
Configuration files are typically stored in `/etc/netcfg/` (depending on
configure options).
Please note that the loopback device is treated specially and not included in
any of the network configuration outlined below. The loopback device is brought
up and configured by a dedicated service long before the network configuration
is done.
## Interface Renaming
If the `ifrename` service is enabled (it is disabled by default), network
interfaces are renamed based on a rule set stored in the file `ifrename`.
The file contains comma separated shell globing patterns for the current
interface name, MAC address and a prefix for the new interface name.
For each network interface, rules are processed top to bottom. If the first two
globing patterns apply, the interface is renamed. Interfaces with the same
prefix are sorted by mac address and a running index is appended to the prefix.
If none of the rules apply, the interface name is left unchanged.
The intent is, to provide a way to configure persistent, deterministic names for
at least all network interfaces that are permanently installed on a board.
Extension cards or external network adapters should be given a different prefix
to avoid changes in the order as they come and go.
## Interface Configuration
After interface renaming, for each network interface, the configuration path is
scanned for files with the same name as the interface.
Each successfully found configuration file is processed line by line, top to
bottom. Each line may contain a keyword, followed by multiple arguments.
The following keywords can be used to add IPv4 or IPv6 network addresses to
an interface:
* address
* addr
* ip
* ip6
* ipv6
Those commands are expected to be followed by an IPv4 or IPv6 address and
network mask.
Furthermore, the following commands can be used for configuring interface
parameters:
* `arp {on|off}`
* `multicast {on|off}`
* `mtu <value>`
* `offload [rx {on|off}] [tx {on|off}] [sg {on|off}] [tso {on|off}]`
* `offload [gso {on|off}] [gro {on|off}] [lro {on|off}] [rxvlan {on|off}]`
* `offload [txvlan {on|off}] [ntuple {on|off}] [rxhash {on|off}]`
* `offload [ufo {on|off}]`
## Route Configuration
After interface configuration is done, routes and rules are restored from a
file named `routes` in the same configuration path.
The file may contain lines starting with `route` or `rule`. Everything that
follows is passed on to `ip route add` or `ip rule add` respectively.
## Net Filter Tables
An additional service is provided that restores the nft rule set from
`/etc/nftables.rules`.

# Interface renaming rules

# Format: NAME,MAC,NEWNAME

# NAME and MAC are shell glob patterns. Both must match for a rule to apply.
# The first matching rule is chosen (top to bottom).

# Interfaces with the same NEWNAME are sorted by MAC and have a running
