Like I said, it's generally not a problem. Since remote installs are typically production machines, I assume you've tested the code you're installing before you do it so there shouldn't be a failure. You might consider doing an NFS mount of /usr/src and /usr/obj from the test machine to make sure you're installing tested binaries. If you've got a serial console you can access remotely (recommended), you can always get to single-user after installing the new kernel by going multi-user then doing a shutdown. I do this for NFS installs, as it's the simplest way to get the network up. If there is a failure in this case, you're pretty much hosed - which is why you test before doing it. Finally, there's at least one VGA/serial card designed for remote admined machines. It turns VGA accesses into ANSI control sequences on the serial line and incoming characters into keystrokes, so you can use the BIOS screens like you were sitting at the machine. http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
