(Please CC any replies to me personally) I don't know if that would work, but if you're running 2.2.5 you may ideally want to be running 2.2.6 or 2.2.7 anyway....? One possibility is to download _all_ the sources for 2.2.6 (or, more likely, 2.2.7), make world, rebuild the kernel and reboot. Total downtime: about two minutes. It's not exactly a 'safe' option, since you're installing binaries in multi-user mode over existing binaries that other users and processes may use frequently. (e.g., if 'make' is halfway through upgrading pppd and someone dials in it's quite possible that pppd will crash - however if they try again a few seconds later it's very likely that they will get through okay). However if I was an end user I'd rather have the odd inconsistencies cropping up over the space of, say, an hour, than have no server at all for a quarter of that time.
