(BTW, I'm running rpm -Uhv to update some packages from another linux machine; I download the updates on it and all other machines load the updates from it.)

I rebooted the machine after this just in case something somewhere might've been unhappy about this. While it was shutting down, the NFS mount point refused to umount, saying the device was busy. The only thing that could've been using that mount point was the rpm command that I ran. I cd'd back to /root before doing the shutdown -r now command. This machine is a dual P2/300 w/320MB memory and no bigmem support compiled in. NFS is compiled into the kernel (not a module) as is the eepro100 network driver. --Scott - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
