A service managed by procd does have a json object with usefull information.
This information could by dumped with the following command.
ubus call service list "{ 'verbose':true, 'name': '<service-name>)'". }"
This line is long and complicated to enter. This commit adds a wrapper
call to the procd service section tool to simplify the input and get the
output faster.
We could now enter the command /etc/initd/<service> info to get the info
faster.

OpenWrt uses a lot of (b)ash scripts for initial setup. This isn't the
best solution as they almost never consider syncing files / data. Still
this is what we have and we need to try living with it.
Without proper syncing OpenWrt can easily get into an inconsistent state
on power cut. It's because:
1. Actual (flash) inode and data writes are not synchronized
2. Data writeback can take up to 30 seconds (dirty_expire_centisecs)
3. ubifs adds extra 5 seconds (dirty_writeback_centisecs) "delay"
Some possible cases (examples) for new files:
1. Power cut during 5 seconds after write() can result in all data loss
2. Power cut happening between 5 and 35 seconds after write() can result
in empty file (inode flushed after 5 seconds, data flush queued)
Above affects e.g. uci-defaults. After executing some migration script
it may get deleted (whited out) without generated data getting actually
written. Power cut will result in missing data and deleted file.
There are three ways of dealing with that:
1. Rewriting all user-space init to proper C with syncs
2. Trying bash hacks (like creating tmp files & moving them)
3. Adding sync and hoping for no power cut during critical section
This change introduces the last solution that is the simplest. It
reduces time during which things may go wrong from ~35 seconds to
probably less than a second. Of course it applies only to IO operations
performed before /etc/init.d/boot . It's probably the stage when the
most new files get created.
All later changes are usually done using smarter C apps (e.g. busybox or
uci) that creates tmp files and uses rename() that is expected to be
atomic.

The following command checks if a instance of a service is running.
/etc/init.d/<service> running <instance>
In the variable `$@`, which is passed to the function
`service_running`, the first argument is always the `instance` which
should be checked. Because all other variables where removed from `$@`
with `shift`.
Before this change the first argument of `$@` was set to the `$service`

If we configure a LED with a non kernel trigger, then we check on every

vconfig has been disabled by default since 2015 [1] and there are
no remaining uses in entire OpenWrt trunk. However, we still set up
a specific name_type for it during boot.
While this setup is properly implemented to be only triggered when
vconfig is present, it still seems anachronistic and unnecessary
to set up a standard for a tool that is not used anymore.
Therefore, this removes the set_name_type initialization and leaves
it for those people actually using the tool to configure it as needed.

trigger will turn the LED automatically on.
Currently LEDs might stay on, e.g. when the LED trigger is set to a
netdev trigger and the interface is never activated or the 'none'
trigger is selected without setting the 'default' option to 0 and it's
set for the LED indicating the system running state.
Using off as a default value is also consistent with the documentation

Due to filesystem write caching the old configuration data could stay
out of flash for a long time during a first boot after the sysupgrade.
Power loss during this period could damage the overlay data and even
make device inaccessable via the network.
Fix this by syncing data to a flash as soon as the previous
configuration will be unpacked after the sysupgrade. Also sync the FS
state after the sysupgrade.tgz archive removing to prevent duplicative
extraction of a previous configuration.

Because /etc/profile (and ~/.profile) are read by login shells only,
aliases and functions defined there are not available to non-login
shells, e.g. when using screen or tmux.
If the ENV environment variable exists (exported by /etc/profile or
~/.profile) and references an existing file, then all interactive shells
(login or non-login) will read that file as well.
This sets the ENV environment variable in /etc/profile, pointing to
/etc/shinit.
This also adds /etc/shinit, which:
* Contains alias and function definitions originally in /etc/profile
* Sources /etc/mkshrc if the user is using mksh (also originally in
/etc/profile), as /etc/mkshrc is meant for all interactive shells
* Sources ~/.mkshrc if the user is using mksh, to compensate for the
fact that mksh will not read ~/.mkshrc if ENV is set
* Sources ~/.shinit if the user is not using mksh
This also removes the shebang from /etc/profile, as the file is sourced,
not executed.

For devices without a dedicated 'diag' LED, we use sometimes one of
other LEDs for indicating at least 'boot', 'failsafe' and 'upgrade'
stages. In some cases, at the same time these LEDs have defined default
triggers in DTS using 'linux,default-trigger' property. Current 'diag'
setup removes the trigger and turns off 'boot' LED after bootup.
One of the examples of such device is TP-Link TL-WR841N v14 (ramips)
which uses 'wlan' LED with defined 'linux,default-trigger' for 'diag':
aliases {
led-boot = &led_wlan;
led-failsafe = &led_wlan;
led-upgrade = &led_wlan;
};
[...]
led_wlan: wlan {
label = "tl-wr841n-v14:green:wlan";
gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
linux,default-trigger = "phy0tpt";
};
This patch extends 'diag.sh' and 'leds.sh' scripts to make sure default
trigger defined in DTS is restored for 'diag' LED which isn't used for
indicating 'running' stage.

Purpose of these changes is to introduce a hook for post service
shutdown in a similar fashion to the existing hook service_started. I
found it to be useful to specify a hook that is called once the service
has been stopped and not before the service is stopped like the
stop_service hook does.
The concrete use case I have for this is that I'm running a binary that
takes over the hardware watchdog timer. Said binary unfortunately can
not use ubus directly to tell procd to hand over the watchdog timer so
this has to be done in the service file for the binary in question. In
order to support a clean handover of the watchdog timer back to procd,
the service init script has to dispatch the ubus invocation once the
binary in question has been stopped.

When restart is run on an init script, the script traps SIGTERM. This is
done as a workaround for scripts named the same name as the program they
start. In that case, the init script process will have the same name as
the program process, and so when the init script runs killall, it will
kill itself. So SIGTERM is trapped to make the init script unkillable.
However, the trap is retained when the init script runs start, and thus
processes started by restart will not respond to SIGTERM, and will thus
be unkillable unless you use SIGKILL. This fixes that by removing the
trap before running start.
