[poky] Running script after installation (postinst)

[Patrick]

Dear all,

In one of our recipes we need to execute a small script after the 
installation of the package. Following yocto dev manual point 4.3.6 we 
have added a pkg_postinst function.

This doesn’t work properly as the script is executed at first start-up 
and not after installation. Below are an example of this recipe.

Do you have any idea why this script is started as first boot time and 
not after installation ?

Thanks in advance for any help !

Patrick
