I suppose you could add to your own /etc/local: dmesg | egrep '(real|avail) memory = ' > /var/log/mem More generally, you may prefer dmesg > /var/log/dmesg.boot instead. I can't see how this is useful, myself. In a situation where I don't know the configuration of each machine by heart, I use a binder to store configuration info. Helpful in the event of a machine failure.
