I'm making a theme packaged on deb.
The theme require to modify some files inside /usr/share/themes/base/meegotouch. It modifies succesfully those file s when i add the script to the posinst file BUT now i want to modify that files by a desktop icon that run an SH script that run commands like /sbin/initctl restart xsession/mthome or symlink inside /usr/share/themes/base/meegotouch/libmeegotouchhome/style but these ones doesn't work.

I don't have permission? I tried chmod +x script.sh on the postinst but no luck

Maybe the script should be placed in other folder? (now is in /opt/theme)
