I'd be curious why a user of Solaris told you that doing a "reboot -- -r" is dangerous, as that command is the method that Sun recommends.
I beg to differ. "touch /reconfigure" and "reboot -- -r" do exactly the same thing. The only thing more "destructive" would be doing a "devfsadm -C" which removes device links that it does not find. I use "touch /reconfigure" exclusive since I will guarantee that the device configure will occur no matter what happens during the shutdown.
