Precisely. Place a file in /etc/sudoers.d with a command that you want whitelisted for running as root via sudo (standard sudoers syntax), instead, and run "update-sudoers" in the postinst and postrm scripts of the package.

Put the equivalent of that into your favourite solution for using D-Bus in an app (DBus-GLib, libosso, python-osso, python-dbus, libdbus, QDBus, ..)
http://maemo.org/api_refs/5.0/5.0-fi...-names_8h.html explains some more of the method calls available to you.

Apologies. It got moved to DSME. Try:

Code:

run-standalone.sh dbus-send --system --type=method_call --dest="com.nokia.dsme" --print-reply "/com/nokia/dsme/request" com.nokia.dsme.request.req_reboot

Qwerty... thats got me thinking, as i have a load of other commands i'd like to run.... - may be best for me to seek alternatives...

apt-get clean
apt-get install pymaemo-optify (possibly)

even looking at using the cleanup script to run externally as part of the application....

# ignoring errors when creating dirs that may already exist

Is this call still valid?

Just not returning anything for me?

Code:

run-standalone.sh dbus-send --system --type=signal /com/nokia/mce/signal com.nokia.mce.signal.sig_device_orientation_ind
