Also, if a package that is currently running has been updated, or that package is currently using a package which has been updated and you want the currently running things to start using the new stuff _now_, you'll want to restart those packages. Until those packages end, disk space and ram memory is not finally freed. Sometimes it is hard to tell if that situation exists and a re-boot is just faster and certainly simpler than identifying, stopping, starting tons of stuff. Often, in a desktop environment, just a telnet 3, telnet 5 command sequence will get most of that done. Faster than reboot, takes care of desktop related stuff without the manual investigate, kill, start steps. > <snip sig stuff> -- Bill
