I think it would be quite handy, if "last" would log the uptime,
before a reboot takes place.

I've seen this on Linux.

Quote from the man page:
"  The pseudo user reboot logs in each time the  system  is  rebooted.   Thus
       last reboot will show a log of all reboots since the log file
was created."

it looks like this:

reboot   system boot  2.6.11.4-20a-smp Fri Dec 22 16:44         (158+00:14)

Here you see the uptime was 158 days +

What do you think about it ?
