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....

Code:

#!/bin/sh
# Nokia N900 Maemo 5 Script to free up space on rootfs
# ignoring errors when creating dirs that may already exist

# Moving themes to /home/opt
mkdir -p /home/opt/usr/share/themes 2> /dev/null
cp -r /usr/share/themes/* /home/opt/usr/share/themes
rm -r /usr/share/themes
ln -s /home/opt/usr/share/themes /usr/share/themes

# Moving ?? icons to /home/opt
mkdir -p /home/opt/usr/share/icons 2> /dev/null
cp -r /usr/share/icons/* /home/opt/usr/share/icons
rm -r /usr/share/icons
ln -s /home/opt/usr/share/icons /usr/share/icons

# Moving video on start-up to /home/opt
mkdir -p /home/opt/usr/share/hildon-welcome 2> /dev/null
cp -r /usr/share/hildon-welcome/* /home/opt/usr/share/hildon-welcome
rm -r /usr/share/hildon-welcome
ln -s /home/opt/usr/share/hildon-welcome /usr/share/hildon-welcome

# ??
mkdir -p /home/opt/usr/share/pixmaps 2> /dev/null
cp -r /usr/share/pixmaps/* /home/opt/usr/share/pixmaps
rm -r /usr/share/pixmaps
ln -s /home/opt/usr/share/pixmaps /usr/share/pixmaps

# Moving 'apt cache' to /home/opt - Valid until Bug 5746 is fixed.
mkdir -p /home/opt/var/cache/apt 2> /dev/null
cp -r /var/cache/apt/* /home/opt/var/cache/apt
rm -r /var/cache/apt
ln -s /home/opt/var/cache/apt /var/cache/apt

Thanks for the save.

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
