Custom live-bottom script not executed

[Cyril Jaquier <cyril.jaquier@jaqpot.net>]

Hi all,

I'm trying to execute a script after my live system boots. I looked at 
[1] and created the attached script. The script is executable. However, 
it doesn't seem to be executed (I don't see any message from it).

Any suggestions?

Thanks.

Cyril
