Hi Caglar,

Hi all,
I have been using RAUC and it is fantastic.
Normally, my system has two root file systems and install other part and
reboots. Nothing special, neither handlers nor hooks. But I have wondered, if I
create a bundle that contains a script and runs that script instead of regular
`rauc install` command. So I created one without any root fs but handler. But
installation failed.
Here is my manifest file:
[update]
compatible=Phytec
version=caglar_v2
description=update-bundle
build=20170711235827
[handler]
filename=/usr/bin/custom_install.sh
args=install
Here is the output of install and log messages:
root@phyboard-regor-am335x-1:/update# rauc install caglar.raucb
trying to contact rauc service
rauc-Message: installing /update/caglar.raucb: installing

hm, it looks as if you have a system.conf that does not have any slots
defined, yet. Is that true? RAUC is not designed for this very special
case it seems and I am not sure if it should support this.
PS: By the way, documentation of handler [1] is out of date, I guess. Group
name is changed from handlers to handler and does not accept key value of
*install. If you explain more, I can update and send you pull request.
Thank you for your help.
Well, this can truely be a bit confusing, but I thing everything is fine
for now.
* [handler]
This section is for the Bundle *Manifest* and its only purpose is to
define a full-custom installation behavior (something that should be
used for debugging or system fixing, only)
* [handlers]
This section is for the *System Configuration* and allows to specify
some handler scripts that can be called during the default installation
routine, for example as pre- or post-install handlers.
Finally, the similar mechanism as [handlers] exists for Bundle
*Manifests*, too. Here they are referred to as [hooks] (to not confuse
too much with then [handler] section).
Hope that pointed it out a bit more clearly?
Best regards
Enrico
