Hi
I'm running 1.2b7 off a CD and floppy and hoping to upgrade to 1.2b9. 
There are likely to be maybe a few dozen users on a WiFi network at the 
time with IP addresses obtained through DHCP.
To upgrade, do I just go to "Reboot System", select "Yes" to reboot and 
then quickly swap the new CD in for the old one, or what would be the 
recommended method? Is there anything I can do to minimize disruption to 
users at the time (who can't be easily notified ahead of time... there's 
no captive portal in use and they're fairly dispersed) like maybe set a 
very short lease time for a while prior to rebooting?
 Thanks,
   - Steve
