I think more important than big uptime, is scheduled
maintenance. I've often pondered the idea of a progie
that captures the uptime and increments a reboot
counter for (and only for) scheduled power cycles.
guess it could be accumulated in a file, but never
seemed worth the trouble.

I can say that uptime roll-overs suck, spent half hour
researching why a Linux box rebooted one day, turns out
to have been on 2**16 seconds, blah. There is a pretty
good bug report for it... my client likes his uptime
so I came up with this hack.

echo $((`cat /proc/uptime | sed 's/\..*/ /'` + 42949673 )) | sed 's/$/ seconds/' | secs2dhms 
578 days 23 hours 56 mins 20 secs

What's the dfly rollover?
