and add this to your /etc/apt/apt.conf to make the remount automatic
when you use apt-get to install or upgrade something:
// Auto re-mounting of a readonly /usr
Pre-Invoke {"mount -o remount,rw /usr";};
Post-Invoke {"suidregister";};
Post-Invoke {"mount -o remount,ro /usr";};
the suidregister thing fixes my customized permissions for
suidregister unaware packages so the cron job don't complain about
failing to do so at 6:25.
