Hi everyone,
I use RAUC on my iMX6 platform. I added handler config option in
/etc/rauc/system.conf file.
[handlers]
pre-install=/preinstall
install=/install
The preinstall and install are shell script file.Then I install bundle
test it.The preinstall has been executed.While the install handler
doesn't execute.And I got the message on below when using debug
option.
Starting pre install handler: /preinstall
rauc-Message: installing /media/update-bundle.raucb: 80% Determining
target install group done.

Using default handler
rauc-Message: Marking target slot as non-bootable...
The rauc use default handler not mine.Did I miss something?
if I understand you correctly, you intend to replace the entire default
installation handler of RAUC? I.e. you only want to use the signature
verification and slot detection of RAUC, but not let it execute its
bootloader interaction, image installation routines, etc? Right?
Would be great if could give a rough sketch of your setup / handling to
understand what is you use case. We gave this option to RAUC users, but
strongly discourage from using it for default stuff, because you will
lose 80% of the benefits RAUC normally provides you.
Now, to make a long story short:
There is no `install` key in [handlers] section of system.conf (see
[1]). Valid items are `system-info`, `pre-install` and `post-install`.
These are handlers that are meant to be executed during *default*
installation process.
The way to replace the entire installation procedure cannot (by
intention) be configured from the system (as it is meant to be used only
for temporary fixups, etc.) but only from the Bundle manifest instead.
Here it will be chosen by providing a 'handler' section with an
appropriate filename an optional args (see [2]):
[handler]
filename=myhandler.sh
This will replace the entire default bootloader and slot installation
handling with calling your script!
Note that there is also the possibility to execute slot-specific install
hooks. I.e. a hook that handles the installation process for a single
slot only instead of replacing the entire installation handling with a
custom script.
Best regards
Enrico
