I hope someday somebody can negotiate a truce between Rich Wales' (UCLA's) postman and UCB's sendmail. =============================================================================== I'm replying directly to you.

SO, this means that you get to >come in between 2 and 6 AM to work on VM. (Dick Dunn) Even though VM has grown an alarming number of features, you can STILL run it in a virtual machine. (Err, *crawl* it in a virtual machine). I used to do that all the time when testing KVM/370, and I did it when upgrading from SP2 to SP3. I don't usually bother for minor enhancements like changing the configuration (DMKRIO). I just wait till most people are at lunch, tell the rest to take a 5 minute break, shutdown, and IPL. There will still be some cases where you have to work at night, of course. If you have a fancy network or other special device that your production depends on and it's not virtualizable and you only have ONE, well that's the way it goes. barry
