Comment 3 for bug 548981

I'm reassinging this to dpkg. I'm not sure that's the right package, but I think it's the right place. In indicator-session we're just watching for /var/run/reboot-required -- but that's what all the other indicators of reboot needing required are looking too. So instead of fixing this in indicator-session we should encourage dpkg/apt to not set the file until thier entire operation is complete.
