My little cash register -- which is doing triple duty as external web server, remote login server and (via the LED-on-a-stick) wall clock -- has served me well:

[root@ext grub]# uptime 12:41am up 193 days, 12:23, 1 user, load average: 0.09, 0.48, 0.41

But the last iptables bug requires a new kernel, and that means a reboot. Goodbye uptime. We'll see you again next March...
