This is not possible as it is an opensuse system script that I cannot

That wouldn't matter. The LSB script is called several times with
different parameters. It always sources another script. In this
script I need to perform an action only at the first time this
script is sourced during the boot process. Thus having a flag 
letting me know that I'm inside the boot sequence would be enough 
to have an unique situation for performing this special action.

If I was able to work with systemd unit files, I could perfectly
do what I want, but I'm stuck with this LSB file.

Isn't there an easy way to figure out if this script is running
inside the boot process? Some variable set or not yet set?
