Hi Enrico,
Thanks for your prompt reply.

In my design , I have to do following things.


-
        Create a RAUC bundle consisting of App images and dbs -> ProductControl.bin, Controls.bin, Operations.bin, ProductControl.db, Controls.db, Operations.db etc. ->Bundle.raucb
-        On installation, both the images and db should go into AppFS. DataFS should remain unaffected.
-        “Post Install Hook” in RAUC shall be used to copy configuration data from the current slot of DataFS to the newly installed slot.


Can we achieve above scenario(with system.conf in previous mail) using  “Post Install Hook” in manifest file. ?


Regards,
Abhishek

Hooks are part of the bundle, thus you have to define them in the bundle's manifest, e.g.:

[hooks]
filename=yourhookscript.sh

[image.appdata]
image=foo.img
hooks=install

Note that your bundle generation has to place yourhookscript.sh into the bundle in order to make this work.


Potentially, you could also do this in a post-install hook for your appfs in case you know where your appdata copies are located.


Best regards,

Enrico

Not sure if I will get in prison when replying on this mail on a world-accessible mailing list... ;)
